It is very useful to know your house well, even though it may seem complicated at first. This includes the power centers, water supply and electric service as well as the gas system. It is impossible to predict when a problem will arise, so knowing how to navigate your home can be very helpful.

Be careful when you are investigating the electrical system in your home. If there is standing water in the room, don't touch it. Also, you shouldn't be using both your hands simultaneously when investigating the electrical system of your home. You can make the panel open by touching it with both your hands. This will allow current to pass through you.

An electric service panel is the control center for the electric current that powers everything in your house, including switches, light sockets and receptacles. An electric service panel is a box made of metal containing fuses. It can be found in an older house. Fuses are shaped like tubes or glass-topped plugs. Toggle switches are found in metal boxes, and these are known as circuit breakers.

These devices are used to prevent electricity from flowing in a circuit when it is unsafe to do so. Although toggle switches and fuses are both circuit breakers, there is one difference: toggle switches turn off automatically when overload occurs. Fuses melt due to overload, thus breaking the circuit.

After such an event, the metal strip must be replaced with a similar-sized and type one. The large, insulated wires that enter your home are connected to the panel. They come from an outside electric meter which is then connected to the company's electricity grid.

If you have toggle switch circuit breakers, you will find the main control that turns the house's electric current on or off. It is usually located above all other switches. However, it is not a rule. You may find the main switch behind a small door that you need to open in order to get to it.

You will need to look for the main fuse if you have fuses. It is located at the top of your box. You will find a number on the main control that indicates what type of service you are receiving. It is usually measured in amps and can be identified as 100, 150, or 200. Sometimes, the main toggle may not be located in the electric panel. It might be in another metal box or in a different place. In such cases, it might be worth calling an electrician to locate the main toggle.

A circuit map can be helpful when the house's lights go out due to an overload current. This involves labeling every switch or fuse with the rooms and switches it controls.
