Beginning about Power Equipment

When electricity was introduced in the budget, is mainly used for lighting. At that time, many power companies controlling a charging system, including the cost of electricity for Power Cords was lower than for other purposes. This took place bulb attached to Power Cords portable devices made.

But as electricity became a common method of lighting houses and operating requirements of labor-saving appliances, a safe way to connect to the network with a different version was a lamp. The electrical properties of two plug pins and socket were invented by Harvey Hubbell and patented in 1904.

Consumers ground several claimants to its invention. The first patent of land appears to be an application on January 11, 1915 by George P. Knapp, on behalf of the Company and Harvey Hubbell granted April 18, 1916. This patent covers the use of a tongue of land that is wider than the two other contacts to ensure that is used for the first time. However, the proposed configuration pins used in type I today, especially in Australia and China, which found no interoperable with the two sheets of contact with the ground. Other records on earth, which is very common today were developed later by others to ensure interoperability with non-grounded plugs.

The security system has been taken by Albert Büttner, who invented it in 1926, patented. The latest American version of the land with two vertical fins and a round grounding pin was invented by Philip F. Labre, while he was here the Milwaukee School of Engineering. It is said that the owner of a cat fan fall when he came through the window was. When connecting the new fan would be a shock. Labre has found that if the plug was based, not the current of the earth through the plug and go to their patron saint. It applied for a patent May 12, 1927 and obtained a U.S. patent for land and taken in June 1928.As the need for more secure facilities clearly grounded systems to three contacts have been made mandatory in most industrialized countries.

Suspected Defects in Power Cords for Medical Devices Spark FDA Investigation

The U.S. Food and Drug Administration is investigating possible defects in power cords used with medical devices from at least two companies, Reuters reported Oct. 19. Abbott Nutrition, a division of Abbott Laboratories Inc., and Hospira Inc., have reported 122 incidents of fires, sparks or charring from Power Cords used with their devices, which include infusion pumps and adult feeding tubes. This can expose users and health care professionals to injury or even death from shocks, fires, and failure of the device while in use. The FDA is warning hospitals and home users of devices to keep an eye on wear and tear on power cords, and stop using cords with visible damage. It also asked users to report any incidents of sparking, charring or fires.

All of the incident reports the FDA has received are about cords manufactured by Electri-Cord Manufacturing Corp. All of the implicated cords use a black plastic “bridge” connecting the plug’s prongs. The two medical device manufacturers, Abbott and Hospira, found that the prongs may fail or crack, either outside the cord or just inside the plastic covering of the plug. The cords have been supplied to other manufacturers of medical devices as well, and the FDA is tracing the cords to determine where else they may be. The problem has already sparked a recall from Hospira; the company initiated a voluntary recall in August, the same month it received a letter from the FDA criticizing its response to the power cord problem. A spokesman for Electri-Cord denied that defects are the problem, suggesting that most cords involved in reported incidents showed signs of “significant abuse.”

I don’t doubt that cords involved in fires, sparking or charring might look abused. However, as a defective medical device attorney, I applaud the FDA’s recall effort, which I hope will prevent further incidents that could seriously hurt someone. Defective cords on any device can be very dangerous because they can electrocute their users or start a fire. (In fact, defective wiring is among the most common causes of house fires.) This may be especially true in hospitals, where doctors routinely use highly flammable pure oxygen during surgery. But on a medical device that patients depend on for nutrition, medicine or other essential needs, faulty wiring can also have serious medical consequences unrelated to a fire or shock. If the device fails, temporarily or permanently, the patient can be deprived of its life-saving effects — which can be at least as deadly as a fire.

The pharmaceutical liability attorneys at the Lowe Law Firm represent people who lost a loved one or were seriously hurt by problems with a medication or medical device. Patients, who generally do not have the medical training to evaluate a therapy on their own, should be able to trust the safety of the drugs and devices their doctors give them. When they are betrayed, they have a legal right to hold the manufacturers of the faulty products legally responsible for their actions. Our medical device defect lawyers represent clients who have suffered a wrongful death in the family or serious damage to their health because of a manufacturer’s negligence. In a lawsuit, we can help clients secure the money they need to treat the damage the bad therapy caused, and compensate them for the financial and personal losses they suffered.

Xbox Power-cord Replacement Program for No-charge

A problem has been found with Xbox Power Cords that can cause burns or damage to the console when submitted to sustain over voltage or mechanical malfunction. The power cords affected were manufactured in the United States before October 23, 2003 or Europe before January 13, 2004.

Power Squids

Power Squids are awesome, as are the 3-way, T-shaped taps that will support three awkwardly-shaped power blocks with one outlet. Those are about a buck at a lumberyard.

Having a device standard for block transformers would mean that people would leave fewer transformers plugged in. It would save energy just from that.

In our storage space at work we have two huge boxes full of hundreds of standard Power Cords – and that’s just one college. I asked the campus Dell rep, in front of all the buyers on campus, if they could please put in a checkbox that said “No power cord” like they do with the documentation and drivers’ CDs, and she said she’d see what she could do. Fifth year in a row, now. Those checkboxes must be really complicated to set up.

Poisonous Lead (Pb) in Electrical Power Cords

Filed Under:
Hazardous Materials
RoHS
Consumer Protection

Did you know that many household power cords contain lead (Pb), a highly poisonous substance? I was recently surprised to read the warning label on an extension cord I purchased.

The adjacent image is a scan of the label attached to an electrical power cord I recently purchased.

Click the image to see it full-size and note the warning regarding the power cord’s lead content.

The warning label says:

“WARNING: The power cord on this product contains lead, a chemical known to the State of California to cause birth defects or other reproductive harm. Wash hands after handling.”

Sadly, many power cords still contain lead. If you use a power cord that contains lead with your vacuum cleaner, you’re potentially brushing the cord over your carpet where your children and pets play. Keep reading – there’s a way around this.

How dangerous is lead? You might want to read this excerpt from Wikipedia or this Wikipedia article about Lead Poisoning. There’s also a group, the Coalition to End Childhood Lead Poisoning with useful information on their website.

Help is On The Way to Remove Lead from Your Life

There is a formal initiative to stop the use of hazardous materials in electrical devices. It’s called the Reduction of Hazardous Substances Directive, or RoHS. The goal is to remove hazardous substances like lead from electrical devices. RoHS took effect in 2006 in the European Union, via EU Directive 2002/95/EC. RoHS compliance is not mandatory in the USA, but manufacturers can voluntarily comply with the RoHS directive at their discretion – and help is on the way.

Not every power cable or surge protector contains lead.

I recently purchased a Tripp Lite Surge Protector, model: TLP602, because the packaging had an RoHS Compliant logo. I subsequently called Tripp Lite to ask them about their RoHS policy and was directed to their website, where I found:

A Series of Tripp Lite Press Releases announcing RoHS Compliant Products and Policy
Tripp Lite’s formal declaration that if they use the RoHS logo on a product, the product will in fact be compliant with EU Directive 2002/95/EC (RoHS)

True Blade will be doing additional research into the use of lead in electrical devices with the goal of helping offices and families stay safe, healthy, and lead-free.

Beware the dangers of daisy-chaining power cords

If you don’t want to run afoul of OHSA, nor start an office fire, you should read this bulletin from federal Office of Compliance on the dangers of linking together (i.e. “daisy-chaining”) Power Cords.

Most powerstrips are approved for providing power to a maximum of four or six individual items; however, when multiple power strips are interconnected, the one directly connected to the building outlet is often supplying power to far more than the approved number. This electrical current overload can result in a fire or can cause a circuit breaker to trip, deenergizing computers and other equipment throughout the area. The risk is magnified when another outlet in the same wall or floor receptacle is also overloaded in a similar fashion. When other outlets on the same circuit are also overloaded, the risk increases.

Among the solutions is this:

In many cases, a powerstrip energized by an extension cord or another powerstrip can simply be replaced by a power strip with a power cord of adequate length to reach an outlet. Alternatively, desks and associated equipment may be moved so they are closer to existing outlets.

You’ll also find some great tips on choosing a good powerstrip with adequate surge protection by reading the full bulletin here.

A big hat tip to Mary Paige Smith, NSU librarian extraordinaire.

Cabling principle

1. Work area subsystem WORK AREA SUBSYSTEM
Workspace subsystem information from the terminal equipment connected to the outlet connection (or cords) composition, which includes assembling the wiring, connectors and extension cords needed to connect, and terminal equipment and I / O bridge between. Information output standards-compliant ISDN RJ45 8-core socket, according to the user’s use of the environment selected embedded, desktop, carpet-type or universal-type socket, according to network terminal equipment interfaces use the appropriate adapter.
2. HORIZONTAL SUBSYSTEM subsystem level
Sub-line stand by the district (IDF) to all the area information output connections. Horizontal cabling subsystem is a part of the entire cabling system that will extend the trunk line subsystem to the user workspace. Route cabling subsystem and subsystem level difference is: in a horizontal cabling subsystem is always on the floor, and termination in the information outlet. SYSTIMAX SCS using 24AWG twisted pair (UTP) for the transmission medium for data and image transmission, using CAT5 twisted pair (1061) or CAT5 + (1071) over five twisted pair, part of the transmission bandwidth and high-speed data have higher expectations of information transfer point,
Can use fiber to the desktop (FTTD) mode settings. Voice and control signals for transmission, using CAT3 twisted pair (1010).
Cable length estimation formula:
LT = [(Lmax + Lmin) / 2 + H] * 1.15 * N
Lmax terminal equipment to the floor farthest distance between the floor device
Lmin terminal equipment to the floor recently the distance between the floor device
H: The floors tall, the height of the program involved to 4 meters.
1.15: cable cut margins and line redundancy for the long length of 15%
N: number of information points in this floor (voice-point number and the number of data points and).

Power Cords

Power line transmission current wires. Typically the current transmission mode is point to point transmission. Power line in accordance with the purpose can be divided into AC and DC power cord AC DC power cable, AC power cord is usually high voltage alternating current through the wire, such wire as the higher voltage needed uniform standards for security certification can formally produce. The DC line voltage is lower by the basic direct current security requirements and therefore there is no AC line strictly, but to be safe, or the requirements for the current national safety certification.

The output power line LAN Connection

Through the power cord to connect high-speed home network established industry standards. Analog Devices’s Curt Wise forecast ,100-Mbit / s HomePlug AV specification will be approved this year by the industry.
For LAN, housing wiring in scope than the wireless advantage. But as a transmission medium, certain aspects of the yet to be improved. Since most CMOS D / A converter provides a current output, an irregular Z0 can convert the output pin voltage swing greatly.
Can be used for conventional applications and for power line LAN output, Analog Devices’s AD9865 (see illustration) to provide differential current output (upper right diagram). They can be directly transferred to an external load or internal low distortion current amplifier. For constant load, current amplifier (IAMP) can be configured for current mode line driver. For the power line, it can be configured for voltage mode (with two external NPN transistor), can generate 23-dBm peak signal 。
