If I have a 15 amp circuit does that mean I can only run one 15 amp rate device on that circuit? Or can I run any number of 15 amp or even higher amp devices, with wattage being the criterion for not overloading the circuit?

Both amp load and wattage are used to limit load on a circuit, amps more often with electricians, since all wire charts , and many other restrictions are listed as amperes in the code books.

Wattage is the product of voltage and amperage, to allow for variables in both values. 15 amps at 120 volts = 1800 watts. #14 generally is wire is rated for 15 amps max, thou there are exceptions.

Increase in amps to 16 amps at 120 volts = 1920 watts. #12 wire is required for any load ove 15 amps.

Wire size is allowed to be smaller than logic is perceived on motors and refrigeration, so if one of those are your concern, let me know and we go over over those details.

Thank you very much for your reply. The reason I asked is that we are planning to buy a small generator for our camping cabin in the country and we have a small refrigerator. The label on the refrigerator says 40 watts. But it also says 15amps. The generator we are looking at has a 15 amp outlet. So I just want to make sure it can handle it and perhaps a lamp or 2 as well?

All the generator info that I find is relating to watts.

Thank you again.
