Yes but it will limit your 20 amp circuit to 15 amps. Any amperage over 15 amps on the 20 amps circuit will trip the breaker protecting the sub panel.

I just spoke with an inspector here in NJ today and according to him pending on what panel(squareD)in this case, it is 24 space but can be 48+. Stating that the breakers allow you to place two branch circuits on one breaker. Didn't make sense to me, being that while in school at my union it was 1 circuit for each breaker. Unless, some tandem breakers are used. Check the breaker and see what its rated for. Hope this helps.

Is a circuit breaker a resistor?

No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.


Why tap in your house gives shock when it is touched or used?

Your water system is not grounded. Turn the main breaker in your distribution panel to off and ground the water system. If a "hot" wire has come into contact with the plumbing, when you turn the electrical panel main breaker back on a breaker will trip. This will give you the circuit that is at fault and a place to start looking for the short circuit.


What is the maximum wire size needed for a typical branch circuit that is protected with a 20-amp circuit breaker?

I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.

What is the role of the main fuse in a domestic circuit?

Power (current, voltage) as supplied by the utility comes in through a main fuse/breaker which is connected to a branch circuit fuse breaker and then goes out to the house's lights and outlets. In the US, the standard for general (those not feeding a specific load, like a stove or dryer) branch circuit is 15 amps (although sometimes 20 amps is used). The main fuse/breaker (i.e., the "service entrance") used to be 100 amps; I think it is now generally 200 amps (though I know of one house that has 600 amps). In addition, there are branch circuits for the stove, dryer, air conditioning, etc., all of which will probably be more than 20 amps. The thing to note is that the sum of all the branch circuits is greater than the ampacity of the service entrance. The difference between the two is based on the assumption that not all of the branch circuits will be drawing their full rated current at all times. The branch circuit breakers protect their wiring against overloads, and the main breakers protect the supply and panel against overloads. This same philosophy is duplicated in (generally) commercial buildings where there are sub-panels closer to the loads. There will be a master breaker for the sub-panel, generally located at the source panel for the supply to the sub-panel, but sometimes at the sub-panel itself.

What is a tandem breaker?

Tandem breakers, often called split breakers or double breakers, provide two separate circuits in the space of a regular sized breaker opening. Every circuit breaker panel has a limited number of circuit openings available. The problem is that when the openings are all used up and you still need to add another circuit, what do you do? You could change the electrical panel or double up circuits on a breaker, but this could place too much load on a particular circuit. So what then? The answer that many have found is a tandem breaker. This type breaker is the same size as any other breaker, but it has its difference. This breaker sports two smaller breakers built into one regular sized breaker. Each has its own breaker switch and the breaker snaps in just like a regular breaker. With this simple innovation, you can add a circuit and protect the circuit on its own dedicated line.
