Can you safely change a 30 amp breaker to 20 amps?
No, this is not a recommended procedure. The breakers main job is to protect the wire that is connected to it. A 20A breaker will have a #12 wire (rated 20A) connected to it. A 30A breaker will have a #10 wire (rated 30A) connected to it. As you can see if you use a 30A breaker on a #12 wire you could overload the wire by 10 amps. I have seen an incident where the insulation has melted off of an overloaded wire, the wire short out and a fire start before the bigger size breaker tripped. DON'T DO IT.
What breaker do you use for 10-2 wire?
For 10-2 wire, you would typically use a 30-amp breaker. This size breaker is commonly used for 10-gauge wire in residential electrical installations. Make sure to check your local electrical codes and the manufacturer's recommendations for the specific application.
Do you need to use some type of mini breaker panel with a single 15A circuit breaker to connect a 15A receptacle into a 30A line?
Yes, you need to use a mini breaker panel with a 15A circuit breaker to safely connect a 15A receptacle to a 30A line. The breaker panel will protect the receptacle and wiring from the higher current capacity of the 30A line, preventing potential overheating or damage. It's important to match the amperage of the circuit breaker with the rating of the receptacle to ensure safe electrical operation.
Is 10-3 wire heavy enough for a washer-dryer combination if they are 50 feet away from the breaker box?
No, for a 50-foot run from the breaker box, 10-3 wire is not heavy enough for a washer-dryer combination. It is recommended to use 8-3 wire for this distance to ensure safe and efficient electrical supply for the appliances.
If you install a 30A 240V GFI breaker will this be ok or will the cycles the dryer has prematurely fail the breaker?
Installing a 30A 240V GFI breaker for a dryer should be fine as long as the wiring and dryer itself are compatible with the breaker. The GFI breaker is designed to protect against electrical faults and should not be affected by the cycles of the dryer. Make sure to follow the installation instructions carefully to ensure proper functioning.

How do you upgrade the service from a 120V 100A circuit breaker to 240V 30A for appliances like ovens and dryers?
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
Does a double-pole 30A breaker pull 15A per leg and if so why can't 14 gauge be used since 14 is rated for 15A?
A double pole 30 amp breaker can pass 30 amps per pole, therefore #10 wire should be used.

In wiring for 220v can one use 2 15a breakers instead of a ganged 30a breaker?
No, when wiring for 220v, you should use a ganged 30A breaker to ensure safe and proper functioning of the circuit. Using two 15A breakers is not recommended as they may not trip simultaneously in an overload situation, potentially causing damage to the circuit or appliances.
Can you plug equipment rated for 50A into a 30A circuit?
No, it is not safe to plug equipment rated for 50A into a 30A circuit. The equipment may draw more current than the circuit can handle, leading to overheating and potentially causing a fire hazard. It is important to match the amperage of the equipment with the circuit it is being connected to.
Will a 20A 240V breaker be sufficient for a 240V 22A input welder or do you need to go to a 30A?
It would have to be a 30 amp breaker to use the full power of the welder. I'd say go with the 30A. The general rule is that your planned load should only be 80% of the circuit capacity. That means a 30A circuit should have a maximum load of of (30*0.8) = 24A. With the 30 amp breaker you must have at least #10 wires feeding the circuit.
Can you change an old 30A fuse box if it has 1r1b1w wire to a 15A gfci for a whirlpool tub outlet?
It is not recommended to change a 30A fuse box to a 15A GFCI without ensuring the wiring is compatible. The wiring with 1r1b1w may need to be modified to meet the requirements for a 15A GFCI and ensure safety. It's best to consult with a licensed electrician to properly assess and make any necessary modifications for the installation.
Can 110V circuit with 2 wire size of 10 and a ground be converted to 220V after changing the outlet and breaker?
No, changing the outlet and breaker does not change the voltage of the circuit. To convert a 110V circuit to 220V, you would need to rewire it with proper gauge wire rated for 220V and install a compatible 220V outlet and breaker. It is important to consult with a licensed electrician for this type of conversion to ensure safety and compliance with electrical codes.
