How many amps does an SINGLE three prong outlet hold?

Answer 1

On newer construction a three pronged outlet where the prong openings are vertical slits are rated for 15 amps. If one of the vertical slits sports an additional horizontal slit, that is rated for 20 amps. This is a total for the entire circuit - whether it is being funnelled through just one outlet or any number of others who may be in the string. (Many residentai applications have one circuit breaker servicing a number of wall outlets (non-major appliance type)).

The 15 amp outlet can be supplied by 14 or 12 awg wire depending on the length of the run. The 20 amp needs 12 awg.

Answer 2

On small single devices the following configurations denote amperage. (Imagine an "o" over the center of the straight prongs).

l l =15 amps l l- =20 amps l - =30 amps

You should however verify the breaker size if you are plugging in something that requires a specific "trip amperage" or a "maximum amperage". Breakers are designed to protect your wires and not what is plugged into them so do not jump up a breaker size to accommodate a certain appliance (wire size needs to increase as amperage increases). Also keep in mind that in US all breakers trip at 80% of there rating (a 20 amp trips at 16 amps)

Answer 3

I assume you really are asking how many amps can you pull from a single 3 prong outlet before the circuit "blows".

It depends on the circuit breaker it is attached to and how many other devices are on the same circuit. Most breakers in the average home are 15 or 20 amps.

---- Edit ---

BTW, "whateverbabe" is confusing amps with voltage.

Answer 4

15 or 20, depends also on the wire guage and distance from the breaker how much amperage you run to the outlet.

For 20 Amp circuits you should run 12 gauge wire.

Answer 5

110 or 220
