Yes you can use a 60 amp breaker to feed a 100 amp sub panel. The wire from the 60 amp breaker must be #6 or larger. You will not be able to draw the maximum 100 amps from the panel you will be limited to 60 amps.

A 240VAC house circuit can be used to power a 50A RV receptacle. It's best to use a 50A breaker or place another (50A) breaker at the receptacle. Each of the two 120VAC, 50A circuits to the RV comes from one of the 240VAC lines. The neutral conductor should be sized as large as the hot.

IMPORTANT ADDITIONAL NOTE

No way should you use any existing 60 amp breaker in your breaker panel unless you are SURE there is no existing appliance connected to it, such as perhaps a clothes washer and/or dryer.

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.

yes, It does not exceed its rating No, The breaker rating exceeds the rating of the 50 amp outlet. The outlet is designed for a maximum rating of 50 amps. To trip the breaker the outlet would have to go 10 amps over its design. You can downsize the 60A to a 50A breaker to comply with the electrical code. The wire connected should be a # 6 which is good for 60A so it will handle 50A nicely.

No, when an amperage is embossed on a receptacle, that is the manufactures maximum limit that the receptacle will legally handle. A 50 amp breaker should be connected to a wire that is at least rated at 50 amps. The nearest will be #6 rated at 65 amps. By connecting a 30 amp receptacle and presumably a 30 amp load down stream from a 50 amp breaker will not protect the 30 amp device safely. It will load the device by another 20 amps before the breaker will trip in an overloaded condition.

A wire that would be protected by a 30 Amp breaker would overheat and potentially cause a fire if it were connected to a 50 Amp breaker.

If you are changing to a higher amp breaker, you MUST run a new circuit that is appropriate if you want to avoid a house fire.

ALWAYS employ a qualified electrician if you are making changes to your electrical system in your home or business.

Not a good idea. A breaker is sized to protect the wire that is connected to it. By installing a larger size breaker you are allowing the conductor that was being protected by the 50 amp breaker to now be protected by a 60 amp rating. This is allowing 10 more amps to be submitted to the conductor than what it is rated for before it will trip. Over a period of time the insulation will become brittle with the extra heating. Once the insulation falls off, the conductors will be subject to short circuits and sparking. Not good.

Yes, a 40 amp breaker can be used on a 50 amp receptacle. What has to be kept in mind though is that the circuits ampacity will be reduced to 40 amps. If a 41 to 50 amp load that uses a 50 amp cord ,is plugged into the circuit it will trip the 40 amp breaker.

No. The the 30 amp rating on the receptacle is the rating that the manufacturer was given permission to use. It is the maximum amount of current allowed to be used. If there is a 50 amp breaker ahead of the receptacle there could be, under certain circumstances, a current of 50 amps applied to the 30 amp receptacle before the circuit opens. This type of installation is contrary to electrical code rules.

It depends on the load in the circuit. If it is 55amps, you shouldn't. Make sure the interrupting ratings match for both.

Is there a adapter for a nema 14-30 plug and a nema 14-50 receptacle?

No there are no adapters made for these types of installations. The reason there are no adapters is to provide a factor of safety. To plug a 30 amp plug into a 50 amp receptacle could allow 50 amps to be applied to a 30 amp rated cord. The 50 amp receptacle is more than likely being fed by a 40 amp breaker. Just change the plug cord to match the ampacity of the breaker ahead of the 50 amp receptacle. Or change the 50 amp receptacle and 40 amp breaker to a 30 amp breaker and use your existing cord plug.


Will your spa work with a 40 amp breaker even if it says 50 amp on the plate?

No, because if you switch a 50-amp load on, it will blow a 40-amp circuit breaker if the load exceeds 40 amps, which is likely.


What is type of breaker for 41 amp's?

50 amp breaker.


Does a double 50 amp breaker make a 100 amp?

No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.


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.

240v nema6-50r outlet wired with 6 gauge wire and 50 amp breaker you need to run a heater with a nema 6-30p can you simply put a 30 amp receptical in place of the 50 amp receptical?

Not legally because the rating of the 30 amp receptacle would have a 50 amp breaker ahead of it. If you reduced the feed breaker to 30 amps and still use the #6 wire, this would be within the electrical code rules.


How many 50 watt lights on a 15 amp circuit?

50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.


Does a double 50 amp breaker make a 100 amp?

No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.


Can you change a 50 amp receptacle to a 15 amp receptacle?

Yes as long as you change the 50 amp breaker to a 15 amp breaker. You will be hard pressed to get the 50 amp #6 wire under the terminals of the 15 amp receptacle.


Can 50 Amp breaker replace 45 Amp breaker?

Both a 45 amp and 50 amp breaker would require 6 AWG wire. So if you have 6 AWG wire and any devices like an outlet are rated at 50 amps or greater you are okay.


How can you push 30 amp breaker to 50 amp?

Not if it's functioning properly. The purpose of a circuit breaker is to shut off power if the circuit exceeds the rated power capacity of the wires. Don't plan to exceed the 30 Amp capacity of your house wiring; the results will be destructive.


What size wire for 75 feet of wire for a 30 amp 220 volt oven?

A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
