== == Getting 40 Amps First, you'll need to run a set of heavier wires from the wall outlet for the water heater back to the main breaker panel - the longer the run is, the heavier the wires will have to be. The wires must have a black and a red as the two "hots, a white neutral and a green or bare ground wire. Then you'll need to buy and install a pair of 240V, 40 amp breakers that match your breaker panel manufacturer.

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.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS. == == == ==

Can you change a double 15amp breaker into a double 20 amp breaker?

Can a double pole 20 amp breaker be used with 12-2 wire for a single 220 circuit?

The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.


Can a double pole 15 amp breaker help?

Help what? A double pole breaker is usually for 220/240 volt applications, but can be used for two 110/120 volt circuits. Also would depend if it is single or double throw.


Can you change 30 amp double pole wiring and breaker to 15 amp?

It is easy to change the 30 amp double pole breaker to a 15 amp double pole breaker. You want to make sure the wires fit. The #10 wires will most likely not fit the device on the other end, unless it is a light fixture and you are using wire nuts. If you are installing a receptacle or switch, or if the load has screw terminals, you will have to splice #14 gauge wire into the #10s so the #14s can to terminated. I have terminated receptacles and switches with #10 wire but it takes a little effort and experience to make sure it is done properly.


Where is the double-pole circuit breaker located?

Yes, otherwise your double pole breaker will shut the other circuit off when one of them trips.


What is a 15 amp double pole breaker?

A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.

You think you blew a fuse in your breaker box how do you fix that one of the two switches are tripped?

I think you are asking how do you fix or replace one breaker on a double pole breaker? Most if not all double breakers have a connector on the switch so that they both trip at the same time. They are also joined together in the body of the breaker. You have to change both of them. If that's not your question, please explain further.
