Answer for UK, Europe and countries running a 50 Hz supply service.

It is acceptable to connect two 15-amp breakers to a 30-amp supply. It woud also be acceptable in some applications to connect three 15-amp breakers if it were known that the total current would not exceed 30 amps. For example in many UK properties there is a 60-amp supply, and connected to this there are two 30-amp supplies for the ring-circuit and the cooker, plus also a 10-amp lighting supply.

Can a 100 amp main have 2 50 amp breakers?

Yes.Additional InformationBreakers and fuses protect the wires to prevent fire. The 100 Amp breaker in the meter base (main) protects the wire from the meter base to the breaker panel. The 50 Amp breaker in the breaker panel protects the wire from the breaker panel to the outlet. Sometimes the 100 amp main breaker is located in the panel.If you are asking "Can you use two 50 amp breakers for the main breakers with a 100 amp service, then yes you can. The National Electrical Code allows you to use up to 6 breakers as the main overcurrent protection.


Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?

Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.


Will a 100 amp breaker box work if there are 5 220 amp breakers and 7 110 breakers?

It will if the 100 amp distribution board is a 20 circuit board. Ten spaces for the 240 volt breakers and seven spaces for the 120 volt breakers. There are two types of 100 amp breaker boards, one rated at 100 percent and the other at 80 percent. Depending on what rating on the panel board you are using will govern the maximum amount of current that can be legally drawn from the board. This breaker board rating will also govern the size of the main breaker installed and the wire size to feed the board, either 100 amp wire or 80 amp wire. The second consideration is what are the connected loads to the breakers, with the total of seventeen breakers, the board can only supply as much amperage as the main breaker will allow.


Can you change a 250v 15 amp breaker with a 115v15 amp breaker?

No, it would not be safe because 250v is too high for that breaker. <<>> In North America all household breakers are rated at 120/240 volts. A 250 volt 15 amp breaker would would be a two pole breaker and take up two slots in the distribution panel. This can be pulled out and replaced with two separate 15 amp breakers or one 15 amp breaker and a slot panel filler to cover the second slot.


Can you had a 20 amp breaker on your 70 amp sub-panel that has already 70 amp total on it that consist of one 50 and two 15 amp breakers and the panel has 4 available spaces out of 8?

How do you get four twenty amp circuits from two twenty amp circuits?

Remove the two twenty amp breakers from the regular size slot and install two mini amp breakers. A mini amp breaker has two breakers per regular size slot.

What does it mean when you have two 30 amp breakers linked together?

Two single-pole 30 amp breakers tied together make a two-pole 30 amp breaker. From this you can power a device that requires 220-240 volts, typically.

Do they make a 30-40 amp two pole breaker compatible with a square d breaker?

No, if you have a Square D distribution panel only Square D breakers will fit in it.


Can you run an extra set of wires off a 20 amp breaker?

No, this is stated very clearly in the electrical code. Only one branch circuit is to be allowed connected to each individual circuit breaker no matter what the amperage is. If a new branch circuit is installed and there are no spare breakers then most distribution panels have the ability to let tandem breaker be installed in it. Tandem breakers have two terminals and two handles and have the ability to fit into a single slot in the distribution panel.


Have existing a 125 amp main need more breakers spaces?

You can swap a single breaker for two mini breakers or you can add a sub-panel. If you only need a couple of extra circuits then just add mini-breakers.


Can you put in piggy back circuit breakers in a circuit panel?

The electrical terminology for this type of breaker is a tandem breaker. It is where two breakers circuits can be in the same one breaker slot in a distribution panel. On this type of breaker there will be two output for a circuit value of what ever the breaker is rated for.


How can you install two - two amp breaker boxes from one meter can?
