What does 115v / 15a mean (electrical) is this equivalent to 120v?

Answer 1

It means 115 volts and 15 amps. In North America, most circuits in your home are going to be 110-120 volts and 15 amps. Technically, 115v and 120v are not equal, of course, but for practical purposes, yes, they are equivalent.

Answer 2

What you are referring to is the rating for an electrical circuit.

For most intents and purposes 120v and 115v AC (alternating current) are the same for an electrical circuit in a space. Your electric power company strives to supply 120 v AC to the space. They call 120v their 'nominal' voltage. But 115v AC will be enough, in almost all cases. In truth I have never encountered an appliance that will not function correctly at 115V AC.

In either case, whatever you connect to the circuit (in total, like lamps, TV, stereo, etc.) is called the 'load'. In a 15a circuit you can hook up a load of 15 amps total before the circuit breaker 'blows' and causes you to make a trip to the breaker box.

Answer 3

Wall outlet voltage in the US can actually vary from 95 to 132V. In electrician-speak, 115V and 120V are interchangeable. Both refer to standard wall outlet service.

The 15A part of it means you can plug it in to your household wall outlet (USA), as long as you don't have anything else plugged to that circuit. The most common USA house circuit is 120V/15A.
