10 amps
If it is a 30 amp breaker then it is a 240 volt outlet.
Remove the 30 amp double pole breaker and install at least one single pole 15 amp breaker. It is best if the other slot is not left open so if you have another single pole breaker of any size install it in the 2nd spot so it isn't open when you replace the cover on the panel. For your 15 amp circuit you need #14 gauge copper wire or larger with a hot, neutral, and ground. Your 30 amp circuit was probably wired with #10 gauge conductors. These will probably work on your 15 amp circuit but it may be difficult to connect #10 conductors to devices.
No, it is not recommended to have a circuit breaker with a higher amperage rating than the device it is protecting. In this case, you should use a 30 amp circuit breaker for a 30 amp air conditioner to ensure proper protection from overcurrent.
If you are referring to a cloths dryer, the answer depends on the requirements of the dryer. Most dryers require AWG#10 wire with a 30 amp fuse. If the wiring is AWG#12 then use a 20 amp breaker but never use it on AWG#10 which requires a 30 amp breaker. If you are referring to a hair dryer then yes a 20 amp breaker is fine.
No. The two appliances usually have dedicated circuits. The range will have a two pole 40 amp breaker and be fed with a 3-C #8 copper cable. The dryer will have a 30 amp two pole breaker and be fed with a 3-C # 10 copper cable. As you can see by powering a 40 amp device from a 30 amp breaker, full operation of the range will trip the 30 amp breaker.
Replace the 30 Amp Breaker with a 15 Amp breaker.
Yes, a 30 amp breaker is a 30 amp breaker. It must however be able to fit the box it is installed in.
The recommended amperage for a 30 amp RV breaker is 30 amps.
The maximum amperage capacity of a 30 amp breaker is 30 amps.
If it is a 30 amp breaker then it is a 240 volt outlet.
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
The appropriate double pole 30 amp breaker to use for a dryer installation is a 30 amp double pole circuit breaker.
