Voltage drop explains how the energy of a voltage source is decreased as electrical current flows through the passive elements (elements that do not supply voltage) of an electrical circuit. The issue becomes important when the length of wire becomes elongated. A common analogy used to explain voltage, current, and voltage drop is a garden hose. Voltage would be the water pressure supplied to the hose. Current would be the water flowing through the hose. And the inherent resistance of the hose is determined by the type and size of the hose, just like how type and size of an electrical wire determine its resistance.
Excessive voltage drop can cause loss of efficiency of light, motors, and appliances. This could result in lights that are dim with a decreased life expectancy for motors or appliances. To avoid excessive voltage drop, select a wire size that will minimize voltage drop. You need to know the length of the wire run and the amp load or current that will be on the circuit. To determine amps, add up the wattage of all electrical devices that will be on the circuit and divide that total by the voltage of the circuit, 110 or 220. Continue reading When The Voltage Drops
Today we’re going to take a look at at a rare and awful occurrence called electrocution, and what we can do in the event that it happens to us or someone close by. Hopefully you’re never in a situation where you have to use this information, but we feel it’s our duty to share it with you as we deal with all things power.

Ahh, Summer. It’s already one of the hottest years on record for much of California, and in light of soaring temperatures, it’s an important time to closely monitor your valuable electronics and data centers. You’ll want to make sure air-conditioning and water-cooling systems are working properly, but there are more steps you can take to ensure your electronics survive the heat.
Fact: Electronic devices tend to run 10-20 degrees higher than room temperature. If temperatures become too hot, outside cooling and ventilation is needed to prevent overheating. While air-conditioning may fit the bill, in some cases you may want invest in an environmental monitoring system to ensure your electronics keep safe. Continue reading How to Protect Your Electronics
It’s that time of year again, when things get a little spooky. The stairs creak a louder, there seems to be more sounds in the dark, and even though you know it’s your neighbor’s dog, you can’t help but think “Werewolf” when you hear it howl at night. The spookiest thing for me, though, is Halloween electrical safety.
With all of your lighting and blow up vampires and ghastly decorations, it’s very easy to get swept up in the holiday spirit. However, Halloween electrical safety is very important. The first thing to check when unloading old decorations is that there are no frayed or exposed wires. Decorations can sit in storage for so long that you never know what little creatures may have chewed through the wire, or what kind of damage they may have suffered. Continue reading Halloween Electrical Safety
I’ve already declared my unbridled love for color, so there is no more of an appropriate time than the present to talk even more about colors. However, in this post, we are discussing conductor colors. In every standard cord, there are three conductors connecting the wires to the proper slot; ground, neutral or live, and providing inner insulation. Matching up each wire to the proper conductor is very important to ensure electrical safety, so each conductor is color coded! Continue reading Conductor Colors
You may have noticed an uptick in the terms “RoHS” and “REACH” compliant. They seem like technical, foreign terms. In reality, though, they’re there for your protection. Quail Electronics is RoHS and REACH compliant, but that probably doesn’t mean a lot to you unless you know what those terms mean. We’ve included a description of those terms, and why they’re important.
RoHS stands for the Restriction of Hazardous Substances directive. RoHS regulations were developed in the UK to promote environmental and human safety. The goal of the RoHS directive is to protect consumers from substances that have been found to be hazardous. RoHS regulations became official on July 1, 2006. While RoHS regulations were initially only used in the UK, other countries have begun to adopt them. Continue reading RoHS and REACH Compliance
Hospitals are great. Sure, they get a bad rap sometimes, but think about it. Everyone who works in the hospital, from the doctors to the janitors, each works together in unison, to try and save people’s lives. Yes, even the janitor. They are responsible for cleanliness, which is the cornerstone of fighting disease. But with so many people relying on so many different electronic devices, it’s important to guarantee power at all times, from operating room machines to power cleaners. That’s where Hospital Grade Lighted power cords come into play! Continue reading Hospital Grade Lighted Cords
Some people have two left feet. I believe that I have two left feet and a third invisible foot that exists only to trip me in very important moments. It’s an issue. During my senior prom, while showing off my signature Hammer moves, I tripped and unplugged the DJ booth and all of the lights, resulting in complete darkness and silence for about ten minutes. In college, while rushing to finish a project, I tripped over a power cord in the computer lab which turned off every single computer, resulting in a sprint for my life as a mob of caffeinated procrastinators chased me through the quad at 3 am. I have ruined countless presentations, proposals, and parties.
For some industries, the importance of maintaining constant power is far more important than my two left feet. Hospitals need to ensure that power can be supplied to operating room machinery seamlessly. Storage facilities need to supply power to all of their mainframes. The OEM marketplace is well aware of the necessity of power supply. But how do you guarantee this? Continue reading The Auto-Lock®: Guaranteeing a Steadfast Connection
Polarization often reminds people of sunglasses, but it’s actually an electrical term as well! Who knew? (Well, I did, but I’m the exception, not the rule). My knowledge of polarization was particularly useful the other day. I was playing a casual game of croquet with my friend, Quincy Quail, when he started complaining about plugs to me, of all things.
“What’s the point,” he asked, “of having those 2 little prong things different sizes? I always try to plug lamps and things like that in, and I end up doing it backward! It’s so frustrating!”
I realized that many people must have this problem and that as a power cord blogger, I have a responsibility to the world to make sure people are getting the most out their sockets, and understand why their plugs are the way they are.
