Overloaded outlets do cause fires -- an estimated 5,300 annually in American households [source: CPSC]. Almost 2,000 of those occur during the holidays [source: ESFI]. Visions of burning sugarplums got HowStuffWorks to wonder -- just how many things can you plug into an electrical outl...
This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the cir...
These PDUs tend to divide the circuit into various branches, each of which operates according to a fuse or its circuit breaker. This alternating phase PDU distributes power on a per outlet basis in the facility. 3. Are the outlets colour coded? To ensure easy identification of circuits, it...
a house and a lot of those appliances are equipped with heaters or powerful motors—such as toasters, electric kettles, slow cookers, coffee makers, stand mixers and many more—making it necessary to have some of the electrical outlets around the countertops capable of supplying higher amperage....
The system of transformers and lines that brings electricity from a power generator to the outlets in our homes or offices is extraordinarily complex. There are dozens of possible points of failure, and many potential errors that can cause an uneven power flow. In today's system of electricity...
I decided to make a wiring diagram of all the house’s electrical outlets, lights, HVAC…. and show the circuit breakers they were assigned to. I have a copy of the wiring diagram taped to the inside of the Service Panel. That has been a real blessing when I need to trouble shoot el...

As a result, if this wire has voltage, it is doing its job! However, be cautious because this clearly indicates that you have not turned off the power to the switch you’re working on. Go to the electrical panel and turn the breaker off. ...
Caution: If the master station connects directly to your home's electrical system, be sure to de-energize the circuit involved and take precautions to prevent someone else from turning it back on while you are working on the circuit. If a transformer is supplied with the master station to po...
The most commonly used electrical cable for indoor wiring is the flat, white plastic type plastic-covered wire, or "Romex" (a trade name). Properly plastic-covered electrical wire is called "NMC" - non-metallic-sheathed cable. . While there are many types and grades of non-metallic ca...
