Hospital-Grade Label

HG LABEL 1Cords used in North America medical equipment must be labeled “Hospital-
Grade.” The plug of this cord is what makes it hospital-grade.

These cords are subject to special requirements in the following standards: Medical Equipment Standards, Power Supply Cord Standards, and Attachment Plug and Receptacle Standards. The special requirement for these standards is that they must be UL and CAN/CSA approved, shown to the right in Figure 1. Continue reading Hospital-Grade Label

The CE Marking

CE rating 1All electronic devices sold in Europe carry an additional feature, the CE Marking. However, the power cord does not require the marking because it is an electrical component, not the finished product. This mark is the “European Conformity”, or in French known as the “Conformité Européenne.” It is essentially the electronic devices passport that allows it to gain access to Europe.

AC & DC — For Those about to Flow We Salute You!

Ever wonder how the Aussie band AC/DC got their name? Or what makes it possible for them to ROCK and ROLL?

There are two types of current flow in a circuit: Alternating Current (AC) and Direct Current (DC).

Have you ever sat down and looked over at your desk lamp and thought, “how does the light come on?” Well, just like every home and office, AC power comes in through the power lines to your home and is what is available to pDifference ACDC 1ower outlets. AC stands for Alternating Current. Your lamp is being powered by AC because of the direction of the flow of electrons. There is a rotating magnet along the wire which causes the electrons to keep switching directions forward and backward. Also, the amount of energy that can be carried through alternating current is easy and also economical to transfer over longer distances and provides more power.

For example: here’s your power plant. It can yield 1 million watts of power. How does this work? Well there’s a way to Continue reading AC & DC — For Those about to Flow We Salute You!

Why You Shouldn’t Buy Male to Male Cords

I’ve read several stories on why people choose to purchase and/or make these male to male power cords, but for some reason, they’re referred to as “suicide cables.”

male to male 1Why? See, power cords have two ends: the male and the female end. The male end is the plug and the female end is the receptacle. When you plug the male end into a wall outlet, the female end or connector is ready to be plugged into a device or equipment, which will allow the electricity to flow through. That is a safe connection. BUT, if you plug the male end into an outlet and have a male plug on the other end, this leaves an exposed conductor (which is the biggest NO-NO).
