How much voltage is 15 amps?

Answer 1

How many watts can be supplied depends on the voltage of the branch circuit.

Because a normal circuit breaker should only be loaded to 80 percent of its trip rating, then 0.80 X 15 = 12 amps.

Assuming a 120 volt, 15 amp branch circuit, the maximum total wattage that can safely be supplied to all appliances connected to that circuit is (120 volts x 12 amps) = 1440watts.

Assuming a 240 volt, 15 amp branch circuit, the maximum total wattage that can safely be supplied to all appliances connected to that circuit is (240 volts x 12 amps) = 2880watts.

However, the 80% quoted is true for continuous loads only. If the appliances being switched on and off on a particular circuit never run continuously all at the same time, their individual wattages when totalled-up can, in fact exceed that 80% figure, because a non-continuously-loaded breaker may have 100% of its rating applied to it for short periods such that it does not become "warm"...

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 2

We don't know what combination of different size/power lights you'll be using,

and maybe you don't know that in advance either.

If you want to keep track as you add lights to the circuit, you should look at the

rated power (watts) on each light, and add them all up. Slow down when you

get near 1,700 watts, and STOP adding any more when you reach 1,750 watts.

Answer 3

The question makes no sense at all.

When calculating amps, watts and volts, you need to know the basic formula:

AMPS * VOLTS = WATTS
