Wiring diagram uses the term "LINE" ?

I have a new timer switch and the wiring diagram uses the term "Line" which I assume is referring to the line coming from the breaker box and not the one going to the light fixture which I believe is called the "load" line. But have not heard/seen the "line" term before and would like conformation before I connect the switch.

Thanks

You’re correct. The line side is the source of power; load side consumes it.

Not sure how the terminology originated but line workers will often say “I’ll work the line side (meaning at the pole) and you work the load side (house connections)”.

For safety, you might want to turn off the circuit breaker (or remove the fuse) feeding this switch. Otherwise, the 'line' side will likely be hot.

Welcome to the forums.

You are correct. "Line" connects to the breaker. "Load" connects to the light or other device.

Edit: Beat me to it by three minutes, Rob!
