If the wall outlet is 15-amp 125V then you'll need either a 20 amp to 15 amp plug adapter or a one foot 20/15 power cord. Each are less than 10 dollars. But if you know how to replace a receptacle, then install a combo 15/20 amp 250V receptacle. Fits perfectly in the same box.
20amp v 15amp
I'm the furthest thing from an engineer so layman's terms would be appreciated. A friend of a friend has an Audioquest Niagara 5000 he's looking to move quickly. The 5000 requires a 20amp power cord, which is fine; I'm happy picking one up. My outlet is only rated for 15amps. My question is, will I only really benefit if I replace the 15amp wall outlet with a 20amp wall outlet?
