When The Voltage Drops

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.volt

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

Universal Adapters

Uni Receptacle

Ever seen one of these and wondered what in the world that is? It is a universal receptacle used for electrical plugs. But not just any, plugs from all over the world! Which is great for all you travelers out there that bring business with you.

A Universal Receptacle features the insertion opening design, allowing it to accept plugs that conform to any International or North American standard. Here at Quail, we offer all plugs from various countries that are compatible with the universal receptacle.

The image below demonstrates a few different cords featuring a country plug on one side and connected to the Universal receptacle on the other.


Now that you are bringing business along with you, I bet you’re wondering about the outlets in that foreign country. This is where a Universal Adapter comes into play. Continue reading Universal Adapters

Amps in Relation to Wire Gauge

SJT wire blueAs my philosophy professor once told me, logic is a fickle thing.  What we often think makes perfect sense never actually does. Those who’ve toiled with justice, love, and the American Wire Gauge system know exactly what I’m talking about.  But no worries; Quail Electronics will explain it all, from wire gauge to the right amperage.  In a previous post, I addressed how the larger the AWG number, the smaller the wire actually is.  This also influences how much amperage is allowed through a wire.

American Wire Gauge vs. International Wire Size

If you grew up in Am1 CONDUCTOR_GREEN_YELLOWerica, meters and millimeters are basically a foreign language.  When I used to read a ruler growing up, I didn’t bother using the centimeter side. Actually, I didn’t even know why it was there. Thinking about it, the one on my desk now doesn’t even have centimeters (I should probably fix that). However, if you grew up on the other side of the pond (or anywhere else for that matter), the metric system is alive and well.

Well with International and North American wire size, it can be just as confusing. For North America, I never understood why as the wire got larger, the number got smaller. Why is 18 AWG smaller than a 10 AWG? Well, back in the day the gauge was determined by how many times the wire had to pass through the drawing dies. The smaller wire, such as 18 AWG, is going to have to pass through more times than the 10 AWG. Actually, makes sense, right? Continue reading American Wire Gauge vs. International Wire Size
