Figure out what you intend to power, and figure out the maximum amount of power you need.
Run one circuit from the house to a subpanel in the garage. Our outbuildings are powered off a 40A 220V supply, to give you an idea.
In the garage, install branch circuits for lights, outlets, etc. This will allow for futureproofing as if you want 4 circuits in the garage, you don't need to run 4 circuits from the house. Also you will have 120/240V just like in the house. (Our garage has a 120V circuit for lights, 2 120V outlet circuits, and 1 240V circuit for the air compresor) It is safer as well as one breaker kills the garage completely. Home Depot sells a nice little Square-D sub-panel for $20 that I have used many times in our outbuildings.
While this may be simply described here, it is actually a big job. Consult an electrician if you are unsure, especially for the high current feed to your subpanel.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.
The voltage is correct, BUT, Your welder is going to draw more current than the pool pump did. The breaker, wiring, and the receptacle will have to be upgraded. In my opinion I have never seen a "temporary" connection!! ...pkazsr
it won't work properly
if i have a breaker that has a 120/240v and my dryer has a 240v plug can i change the receptacle to a 240v
Can run 208v heater on 240v?
Yes you plug a 240v appliance into 220v receptacle.
Disregard the neutral
It May Fuse It Or Not Charge The Battery At All
No ... there isn't enough current (amperes) to properly power up a 240v appliance on 110v. Besides, the plug configurations are completely different.
to turn on a 240v or480v system,like a 240v waterheater
yes, 31watt divide 240v equals to 0.13amps.
Yes, you can plug a 240v motor into a 230v outlet.
Probably not. The average dryer will pull 25amps.
Very definitely - YES it can - although not everyone who gets a 240v shock will be killed.
For a 7000watts or 7kw a 240V then it is 30 Amp
watts = volts X ampsSo240V X 10A = 2400W - not 2500.
With a transformer.
No, You will need to run an extra set of wires.
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
