Load is the wire going from the switch to the device. Load will only be hot if the switch is closed. I really don't like using analogies from plumbing, but imagine a spigot and hose. The pipe coming out of the house is like the line wire: always pressurized. The spigot is the switch, and the hose is load.
Load vs. line wire. A delayed timer switch I am installing requires that a different wire be fastened to the "load wire" than to the "line." How would I determine which is which (both come into box at same side). Can I use a multitester? Remove Advertisements. Sponsored Links
Distinguishing between line and load isn't always necessary. For example, a conventional wall switch -- which is a single-pole, single-throw switch -- works equally well whether you attach the live circuit wire -- line-- to the top brass terminal or the bottom because the switch has only two positions -- open or closed.The terminal connections are directional on a double-throw switch, on the ....
What Color Is the Load Wire? In a circuit, the main load wire — the live power wire between the switch and power source — is typically black, and the secondary load wire is usually red. Wire colors can vary between circuits, so it is best to remove or turn off power sources before touching them.
Line and load refer to the power connections coming into or out of electrical devices in the scheme of your electrical system. It's all relative because, in many cases, the load wire of one device is the line wire of the next device in the circuit. In this way, the terms can generally be thought of as "incoming" and "outgoing."
What does it mean when one wire goes into load, and one goes into line. ... The previous outlet that was there, had the white wire going into the silver load terminal-- while the black wire was going into the brass line terminal. There was only 2 wires connected.
Sometimes the simplest things, like knowing “line vs load”, are the most useful. Especially for apprentice electricians. Knowing the difference between the “Line” and the “Load” side of things is one of those simple pieces of knowledge that can save a lot of headache, and a lot of hazing from your j-man or master.
# 22 A very quick look at the difference between line and load and how it applies to an endless list of electrical devices. A must watch for smart switches, contactors, photocells and other ...
Best Answer: The load wire should be without power until you finish connecting everything in the circuit. The line wire should have power until the breaker is turned off. The load is the wire to the device that consumes the electricity. A lamp, a radio, or the device where they can be powered by being ...
