Pay Attention to Power Cord Types

I had to bring my car into the shop yesterday for a repair to my blower motor. The motor was malfunctioning, and it was drawing more power than the connectors were designed to handle. The technician at the dealership said that this caused the connectors to melt, which has prevented my blower from working. The real problem here is with the blower, not the connectors, and if I temporarily fix the connectors, the blower will work again until the connectors melt again. But after discovering that the car’s undercarriage has completely rusted out, the front wheel bearings are loose and the engine is Continue reading

The Value of Power Cord Manufacturers

Power cord manufacturing is underrated for its importance to our economy. Power cord manufacturers belong in a class with other manufacturers whose products and services form an infrastructure that supports the rest of the economy. Think about why this might be the case. Our economy has become entirely dependent on electricity in order to function. Basically every household and place of Continue reading

Extension Cord Safety

Not all extension cords are created equal. This much is clear to anyone who looks at two different extension cords with different wattage ratings. The American Wire Gauge System is the system by which industry professionals assign extension cords with number values that correspond to their wattage capacities. In that system, all extension cords are assigned gauge numbers. The higher the gauge, the smaller the cord’s diameter and its wattage capacity. These numbers are important indicators of an extension cord’s performance, but they are, unfortunately, often Continue reading

When Bulk Wire is Better than a Cordset

Many companies that offer cordsets, receptacles and other power cords and accessories also offer simple bulk wire. There are a number of situations in which access to bulk wire without plugs could be desirable, though companies that make or sell power transmission cords tend to emphasize cordsets in their product lines. Seeing why bulk wire could be more desirable than cordsets, though, can be Continue reading

Screw Terminals: Reliable and Easy to Use

Some power cord manufacturers are also sources of other kinds of electronic connection utilities. Screw terminals, for example, are sometimes produced or distributed by companies that also produce or distribute power cords. For those of you who may not be familiar with screw terminals, they are composed of at least one row of conductors, each of which is connected to a discreet electrical circuit, and each of those conductors is fitted with a threaded fastener. The fasteners are used to Continue reading

Two-Pronged Plugs: Infinite Frustration/Safety

One of the greatest household frustrations (in the minute frustrations category, that is) is reaching to plug two-pronged plugs into outlets. Two-conductor power cords are still prevalent in consumer and even commercial and industrial contexts. While it’s true that a grounding pin is an important safety feature in many power cords, it is not always necessary. In addition to its benefits as a safety feature, though, the grounding pin in a three-prong plug serves another purpose. There’s no guessing about Continue reading

Why Grounded Power Cords are Necessary

There are some frustrations that come with the territory of living in an old house. I live in one of four apartments in a house that was built in the 1890s. It’s a nice-looking Victorian, complete with radiators instead of forced-air, buzzers instead of door bells and highly-ornate, ungrounded outlets instead of grounded, highly-functional outlets. Some of my outlets are even arranged in a pattern that I don’t think gets made any more (the prongs, I would imagine, would have to be arranged in a cross shape). To my chagrin, every time I go to plug in a cord with a grounding pin, I have to check around the other outlets to find my grounded pin adapter, which makes a grounded cord connectable with an ungrounded outlet. Why are grounded connections Continue reading

Power Cords vs. Wireless Power Transmission

Increasingly, people seem to be talking about the possibilities presented by inductive charging. Instead of involving the direct connection of conductive materials, inductive chargers are considered to be wireless because they transfer energy via electromagnetic fields. Wireless power transmission is a novel technology, and it seems like it could elevate the prospects for new, high-technology industrial and Continue reading

Hospital Power Cords – Meeting the Needs of Healthcare Facilities

The need for power cords is ubiquitous (see the above video to learn about the different kinds of power cords). However, the kind of need can vary depending on location and application. Different applications call for different kinds of power cords. The nature of the need varies from situation to situation, and the response to that need also varies. In informal contexts, particularly in the case of consumer contexts, responses to specific power cord needs can be improvised. But in rigidly controlled contexts, such as in hospitals, power cords often must be made to meet rigidly set Continue reading

IEC Power Cords – Compatibility Guaranteed

There is only one kind of electricity, and that is electricity. It can be generated in an incredibly wide variety of ways, and the number of different ways in which it can be transmitted between places is equally diverse. But electricity is electricity. In light of that fact, it seems strange that we’ve found so many ways to facilitate its transmission between places. There are too many different varieties of cords and cord sets to count. They vary widely depending on geographical location, and Continue reading
