How do you wire a 4-wire to a 3-wire?

Connect the ground wire of the 3-wire cable to the ground wire of the 4-wire cable. Connect the black wire of the 3-wire circuit to either the red or the black wire of the 4-wire circuit. The red and black wires are the”hot” wires. Either wire can be used to power a circuit.

What is the difference between 3-wire and 4-wire?

3-wire is the industry workhorse for good reason. It provides solid accuracy that typically exceeds industrial needs and is the most economical with respect to simplified electronics and less wire (more on this below). 4-wire will give you better accuracy, especially with long wire runs.

What is a load wire on a timer switch?



The hot wire connections for a mechanical timer switch include both a LINE and LOAD connection. The LINE connection is where the incoming hot wire from the power source is connected, while the LOAD connection carries power onward from the switch to the appliance or device.

Which wire is load and which is line?

Load Wire – Generally connected to the top half of your switch. If the wire is coming from the top of the switch box, it is likely your load wire. Line Wire – Generally connected to the bottom half of your switch. In some cases, line wires are marked with “line”, “pwr”, or a lightning bolt symbol.

What happens if I mix up line and load?



If the load and line wiring gets messed up, a ground fault (radio in the tub) won’t trip the GFCI. There is no protection; there’s only the appearance of protection. The GFCI is a booby trap.

Is load wire white or black?

black

So, what color is the load wire? Load wires are mostly black, but red can also be used as a secondary load wire. They are also connected to the switch’s top half, while line wires are connected to the switch’s bottom half.

How can you tell which wire is hot and load?



The easiest way of identifying the line/hot and load wires is to check the colors of the insulation. White and grey wires are neutral; green with yellow stripes, green and copper are ground wires, black can be line/upstream wire, red or black are load/downstream. The white or black are travelers.

Which wire is hot if both are black?

The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.

How do you test if a wire is live with a screwdriver?

Touch the tip of the tester screwdriver to the wire you’re testing, being sure to hold the tester screwdriver’s insulated handle. Look at the handle of the screwdriver. If the small neon light in the handle lights up, there is power going to the circuit. Otherwise the circuit is dead.
