Adding Electrical Circuit Fuse Box

If you follow our safety steps in order and to the letter you ll be fine.

Adding electrical circuit fuse box.

Opening the main circuit breaker panel box and adding a circuit is actually pretty easy. Certain slots in electrical panels will accept tandem breakers or a split breaker but not all slots. By removing a standard 20 amp breaker and replacing it with a tandem unit that has two 20 amp breakers you immediately gain an extra circuit in the electrical panel. The wires from the original breaker are attached to one of the new breakers in the tandem and the wires feeding your new circuit are attached to the second breaker.

The top slot is for your new fuse. If you are adding a circuit in a room with finished walls you will need to use fish tape to run cable behind the walls from electrical box to electrical box. It connects the input or the positive terminal of the battery to your new device and closes your new the circuit 7. The bottom slot of the add a fuse adapter is for your original fuse 5 that as usual completes the original circuit 6.

But there are some safety precautions and if you ignore them you could kill yourself. Learn more in our running electrical wire behind walls project guide. If a dedicated circuit is required or it is really to big to take of a rfc and as you say your existing fuse box is full then an electrician will fit a stand alone smaller fuse box just for this job the same as they may do for an electric shower or perhaps an outbuilding.
