I have a circuit that is now 240v and I wish to change it to 120
volts. The switch that trips the fuse at the circuit box for that
curcuit consists of 2 switches connected together with a clip. If I
were to remove the clip and put one switch in the off position
permanently and the other one in the on position would this be a safe
and sound way to get 120v from this circuit? Would it matter which one
I used for the on circuit? Is this the right way to do this? Sorry if
this sounds ludicrous, I don't know much about electricity in a home.
Assuming it's a two wire cable with a black and a white wire on the double
pole breaker, you would remove the white wire from the breaker and install
it on the neutral buss. Next, remove the bridge connecting the breakers
together. Now you have a 120 volt circuit
Your lack of knowledge is a scary thing. We could give you lots of
great advice, but your probably ought to have someone with more
experience walk you through the process, in person. 240v is no joke,
you could be taking your life into your hands.
What is the 240v circuit for? Why do you want to change it to 120v? What
is the cable? Are there outlets involved?
The advice you were given might work, or your method might work; or it might
be a really stupid thing to do.
You didn't give enough information.
You're confusing switch and breaker, and it's giving me a headache ;-)
It'd be best explaining better what the circuit is currently
doing, why you want to switch it, and other details. Like,
does the cable the tie-barred breaker have 3 or 4 wires in it?
What is the amperage of the breaker?
[From a theoretical/code perspective, some of the questions are
irrelevant, but they may shed some light on the wisdom of doing
this at all.]
