Usually copper, sometimes gold or silver.
A circuit breaker does not have a wire fuse in it.
Yes, you install a GFCI on a 2 wire circuit.
No. In a 20 amp circuit all wire has to be 12 AWG or larger.
mini-hydraulic
No. The wire size is dependent on the circuit protection. If the circuit uses a 20 amp breaker you need to run 12 AWG wire on all devices connected to that circuit.
There is a complete circuit.
A "hot" positive wire has made contact with ground = short circuit.
Factors that contribute to the resistance to the flow of electricity in a circuit include the material the wire is made of, the length and thickness of the wire, and the temperature of the wire.
The common wire in a typical electrical circuit is the neutral wire.
The type of wire does not generally determine whether something is a ground wire or not. A wire is a ground wire if it is connected to the ground of a circuit, or the common ground (the reference point of a circuit that is at 0 volts). However, in relation to the grounding rod used to connect the main circuit panel for a house, the rods are almost always made of steel that are copper plated.
A fuse in its simplest form - is simply a short piece of wire that is weaker than the circuit it is protecting. When the current flowing through the circuit exceeds the fuse rating, the fuse wire melts - breaking the circuit.
A circuit breaker does not have a wire fuse in it.
The wire comes from the installer or manufacturer of the circuit.
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
we can make an open circuit by disconnecting the wire or break the circuit and a closed circuit is made by connecting all wires with the contents of the circuits.
In an electrical circuit, the black wire is typically designated as the hot wire.
In an electrical circuit, the white wire is typically designated as the neutral wire.
