How do you wire a 15 amp breaker for 240v?

Answer 1

A single pole 15 amp breaker can only be setup for 120v. You need a double pole 15 amp breaker, which looks like two 15a breakers attached with a bar across the two actuators. Each leg provides 120v, or in the case of your breaker, 240v across the two legs.

Answer 2

This is a job which should be done only by a professional licensed electrician.

Do not attempt to do this if you have not undergone proper training in the safety procedures which are necessary when doing work on electrical installations.

In many countries, states, counties, cities and towns it is now illegal for anyone who is not a licensed electrician to attempt to do any work on the main breaker panel at the service entry point of any building or other work site.

Before you can start to do any electrical work in your own home, in some countries, states, counties, cities and towns it is necessary to obtain a Homeowner's Electrical Work Permit. Such a permit will only be issued to you if you can demonstrate to your local Building Codes Officer that you understand the rules laid down in both the NEC (National Electrical Code) and also any local Building Codes which apply to your home's location.

If you ignore your local laws about this or if you do the work in an unsafe or incorrect manner:

a) Your home insurance would be rendered invalid so that you will not be able to claim insurance compensation to cover any home fires, personal accidents or injuries caused by electrical work done in an illegal, unsafe or incorrect manner.

b) If any kind of incident occurs following the work, no matter whether it is a home fire or injury to any person(s), you risk being prosecuted by the local authorities for criminal negligence.

c) Someone receiving an electric shock, someone being killed by electrocution or a home fire could be the unintended results of your illegal action.

d) You are not only risking your own life but the lives of other members of your family, of visitors to your home and of future buyers of your home!

Another answer

The very first thing you do is shut off the main breaker. This is a must. Now take your flashlight and remove the cover. Establish whether the breaker is a push-in or bolt-in. If it is a bolt in you will see the bolts in the center buss bar. Disconnect the breakers connected load. If push-in pry out and snap in new breaker. If bolt-in unscrew and replace breaker, do not over tighted and strip the tapped hole. Re connect the load circuit. Re install panel cover. Turn the main breaker on. Keep in mind that if you accidentally short the main buss you can get severe arc flash with 3rd degree burns.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.
