# Electrical Wiring 101 Understanding Circuits Basics

### In general the utility company s jurisdiction stops with the meter.

Electrical wiring 101 understanding circuits basics. Atoms that let current flow easily are called conductors whereas atoms that don t let current flow easily are called insulators. Wiring a 4 way switch. In an incandescent bulb the current flows through a thin tungsten wire or a metallic filament that offers high resistance to current flow. When the electrons bump into.

Direct and alternating current. Wires running inside nm cable bx cable or conduit are sized according to each circuit s amperage. Ampacity and wire insulation according to the electrical code the overcurrent protection shall not exceed 15a for 14 20a for 12 or 30a for 10 however insulation is a factor in locations above 86 f wire and circuit breaker sizing for motor loads. At 0 degrees the voltage is at 0 volts and starts to rise to a peak voltage of 170 volts at 90 degrees.

This refers to the point in your home where your electrical service goes from the main grid into your home. When working with electricity. Between the two hot wires it will read 230 volts. Residential electrical wiring systems start with the utility s power lines and equipment that provide power to the home known collectively as the service entrance.

If you try to strip wires using a knife instead of a stripper you probably will nick the copper and weaken the wire. For example wiring for 20 amp circuits is 12 gauge which is heavier than the 14 gauge wiring used for 15 amp circuits. At 90 degrees the voltage goes back down to 0 volts at 180 degrees. The power is run through an electric meter which records how much energy is used in the home and is the basis for the monthly electric bill.

Besides safety considerations and regulations the other thing you want to familiarize yourself with is the make up of your home wiring. If a voltmeter is put between either of the hot wires and the neutral it will read 115 volts. Circuit basics circuit basics is the idea that a circuit acts as a path for electrical currents to flow through. Before beginning electrical work gather a basic set of tools designed for wiring.

It boils down to three basic components. Two or more 115 volt circuits can be taken from it and one or more 230 volt circuits. Twisting wires together using a pair of household slip joint pliers is difficult and the loose connection might come apart. A battery a lamp and an electrical wire that connects the two.

It is really a two wire 230 volt single phase circuit with a neutral. Wiring diagrams for 2 way switches 3 way switches 4 way switches outlets and more. Learn more about other circuit basics in this section. For example a very simple electrical circuit consists of three elements.

Electric current flows more easily in some types of atoms than in others. Wiring a 2 way switch how to wire a 2 way switch how to change or replace a basic on off 2 way switch wiring a 3 way switch how to wire a 3 way switch how to wire a 3 way switch circuit and teach you how the circuit works. An electric circuit is a closed loop made of conductors and other electrical elements through which electric current can flow. The lower the gauge the larger the wire and the more current it can handle.
