Most apartments have a 60 amp panel for their electrical distribution.
For a 50 amp hot tub installation, a double-pole 50 amp breaker is required.
The maximum current rating for the circuit breaker required for a 125 amp load is 125 amps.
A minimum of 15-amp breaker is "needed", but a 20-amp is often required by electrical code for that situation.
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
The maximum current rating for the circuit breaker needed for a 60 amp electrical load is 60 amps.
A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.
Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
Replace the 30 Amp Breaker with a 15 Amp breaker.
maybe 10 amperes
No, you should not replace a 15 amp breaker with a 20 amp breaker without consulting a licensed electrician. The breaker size should match the wire size to prevent overheating and potential fire hazards.
A 50 amp breaker is an overcurent device.
For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
