Wires used in appliance cords are of different diameters, or gauges. The thicker the wire, the lower the gauge number. That is, a 12-gauge wire is thinner than a 10-gauge wire. Most small appliances use cord wires of copper strands insulated with heat-resistant plastic. An appliance that...
If a 14-gauge wire is connected to a 20-amp circuit breaker or fuse, replace the breaker or fuse with one that is 15 amps to prevent the wire from overheating. In most cases, a 20-amp fuse or breaker should connect to a 12-gauge wire; a 30-amp fuse or breaker should connect to...
Mount the converter in a closet or under a dinette seat. Connect the wiring from the output side of the converter to your deep cycle battery. Connect the 14 gauge stranded wiring from your 12 volt lights and waterpump to the battery. Wire the input side of the converter to one of the ...
Take your red, green, and white wires (10 gauge wire size) and insert them into the electrical panel and the weatherproof box. For the weatherproof outlet box: The hot wire goes into the copper connector. The neutral wire goes into the silver connector. Insert the ground wire into the gro...
When looking at a charge controller, there are a range of things to examine on its list of specifications or label. A PWM controller will have an amp reading for it, for example 30 amp PWM controller. This represents how many amps the controller can handle, in the case above, 30 amps....
Transistors had many advantages: high reliability, low power consumption and small size compared to tubes or relays. These transistors were discrete devices, meaning that each transistor was a separate device. Each one came in a little metal can about the size of a pea with three wires attached...
In fact, both the HU and amp lead can be tapped from the same bolt on the stock + battery terminal, as shown below. I used 16 gauge wire for the HU constant power. Here's a larger pic showing the power wiring for the head unit and amp. Note the fuses, 60 amp for the amplifier...
Do you need to plug in an electric kettle, a floor lamp, or a refrigerator? In all of these cases and many more, you'll need a 120-volt power outlet, more correctly called a 120-volt receptacle. Every house in North America has them unless the house happens to be off-grid and powe...
A multimeter is an electronic measuring instrument that is used to gauge volts, amps, and resistance from an electrical source. The most common automotive application for a multimeter is to test the strength of a car battery. When used properly, it will provide voltage information to a high de...
How Many Receptacles Can Be on a 20 amp Circuit? Effective load management is necessary when adding new outlets to a circuit. To compute the outlet count, multiply the amps with volts to get how many watts the circuit can support. Most countries, including the USA, use a 120-volt circuit...
