How do you change over so you can plug a 120V RV plug into a 240V single-phase twist-lock receptacle?

Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4) If your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase. If the case is the former you can't get 110V off that plug.

Can a 130W fan be installed into a 120V outlet?
Yes, a 130 watt fan can be plugged into a 120 volt receptacle. The current draw will be I = W/E, Amps = Watts/Volts = 130/120 = 1.08 amps.
Can you convert a 30 amp 120V RV receptacle into a normal 120V outlet?
You can, but your circuit will be "protected" by a 30 amp breaker. So you'll have to consider the safety issues of having wiring and appliances that can draw up to 30 amps before tripping the breaker. Will the wiring and circuity support that much current without damage? If not, then switch to a 15 or 20 amp breaker.
Does the NEC code allow multiple 20A receptacles on a 20A circuit Put another way does a 20A receptacle with T shaped neutral slots imply that no other outlets are that circuit?
The National Electrical Code (US) allows up to thirteen 20 amp receptacles on a 20 amp circuit. 120V x 20A = 2400 VA each duplex receptacle is calculated at 180 VA 2400 / 180 = 13.3333 receptacles, since you can't put a third of a receptacle in, you have to round down to 13.
What adapters do you need to plug your 240V Ac plug into a 110V AC supply?
There are no adptors to plug a 240v plug into a 120v receptacle. 240v requires two hot wores and a neutral and ground. 120v requires one hot wire, a neutral and a ground. If you have something that runs on 240/120 you need the cord and adaptor that came with the equipment as you willl need the wires to mate up accordingly.
How do you convert a 120V receptacle to a 240V receptacle for a European stereo system that uses 230V if the Stereo has no toggle switch to 110V like some units on the market?
You can't "convert" a 120V receptacle into a 240V receptacle.A proper new 240V branch circuit complete with correctly sized circuit breakers, wiring and socket outlet is required.For more information see the Related Question shown below.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
I have 240V 3 wire twistlock plug and want to wire it so I have 120V outlet?
Don't!
How can you wire one half of a 20 amp 120 v duplex wall socket to run 240 volts over 2 legs 2 separate 120 v legs?
You can't. I'm not sure exactly what you're trying to do, but the way it is written is not possible. It seems you might want to use half of a duplex receptacle for 120 and half for 240. This would not be code compliant, nor would it make sense. A plug designed for 240v will not even fit into a 120v receptacle. You need a 240 volt receptacle rated for the amperage you will need. Also, an existing 120v receptacle has nothing to do with your 240v receptacle. For a 240 volt receptacle, you'll need to run 2 new 120v lines (in the same cable). The existing 120v circuit cannot be used here, even if you added another 120v circuit, because when a load uses 240v, both 120v circuits supplying the 240v must be controlled by a common disconnect (a 2 pole breaker designed for 240v circuit). My advice would be to show an electrician what you want done. I'm sure they can tell you how to make that happen.
Can you plug 230 volt 60 Hz 4.8 A pump into a household receptical with a GFI breaker?
No. A household receptacle is 120V. It will not work.
Why would someone use two positive wires to complete a house 2 plug receptacle circuit?
If the 2 hot wires are connected to either side of a receptacle, you have a 240v receptacle (assuming it's in the US). This is typically done for window air conditioners. But code requires that the receptacle have a different configuration than other receptacles in the building so you don't run the risk of plugging in a 120v device into a 240v receptacle.
Change l5-30 plug for l6-30 plug?
It's the same receptacle, except L6 is 240V rated vs 120V rated for L5 (note: The answer above is incorrect. It is true that the L6-30 is a 240V rated connector, and the L5-30 is 125V rated. However they do not share the same pins, they are similar, but one connector will not mate with the other receptacle.)
Can a 120V 20A non-locking plug be replaced with a locking-type plug of the same rating without affecting the performance of the appliance?
Change the receptacle and the plug is the best way to do this. Provided you use a properly rated plug, changing the plug type will not affect the appliance at all.
What is the proper type of meter for testing a GCFI receptacle?
Any electrical meter which measures volts or a standard plug tester. (the ones which plug into the receptacle and light up indicator lights) As long as the receptacle measures 110-120V between the hot and neutral, and measures 110-120V between the hot and ground, then it is wired correctly and supplying correct voltage with ground reference. To determine if the GFCI is "tripping" or opening the circuit when it should, simply press the test button. If it doesn't trip, (or reset correctly with the reset button) replace the device.
How do you wire up 2 120V strands into a 240V if the 3 prong receptacle has 2 hots and a neutral but no place for the grounds and should you just wirenut the grounds and tuck them in the box?
On the three prong 240 v receptacle there shouldn't be a neutral because it's not needed. Should be two hots and the ground and tuck neutrals in box.
