How much voltage does a house need?

Answer 1

240 volts; 120v positive, 120v negative, and neutral.

Answer 2

In the US, homes are wired for 110 volts, or 220 volts. (2 110 V. runs, and a neutral.) This helps if you have heavy washer/dryer, or A.C. needs.. The extra voltage requires less current. Actually it's not really the voltage that counts, it's the amperage, or current. Depending on how much 'drain' or amperage usage, relates as to the wiring and proper size cables to each outlet. The old days were mostly 10 amp. plugs. Nowadays, most all sockets are rated 15 to 20 amps, with a ground pin also. 220V. operation is provided for washers, dryers, a.c., etc.

Answer 3

110 volts runs to a USA house. House fuse or breaker boxes are in amps 100 is in most. Older house had 40 to 60 amps. If you will use a lot of power. Need higher amp. In my house I have a 125 amp box. Come in higher amp boxes too. Depends on what you are running in your house now. Stoves and dryers use 220 volts. But you can get that from a double breaker (or fuse in older boxes that should be up dated) 220 v. uses a black, red, white and green wire. The black and red wire is hot the white wire is natural and green is ground. 110 only uses black, white and green.

So to help you answer your question. If you have big items ticket items that use a lot of amp you will need a larger breaker box with 100 amps or more. But all usa house only have 110 volts going to them.. Only a fell have 220 volts and that's mostly for people that use a lot more amps for 220.

Breakers or fuses also run in amps from 10 amp to 60 amps some even go higher.

Answer 4

Standard supplied voltage to residences is 240 volts ac. Are you sure you're not meaning amperage required for standard residences? Anywhere from 100 (gas and electrical appliances) to 200 (total electric) is standard.

Answer 5

240 amps

Answer 6

depends where you are...

UK 220V
US 110V
