Why when I Check ohms from ground to both 220v legs do I get a reading of 18 to 21?
With the power off? If you are looking at transformer terminals on an unpowered unit you would be seeing the coil resistance. You should not use your meter in the ohms setting with voltage present. It wasn't designed for that. Measure voltage from ground on a 220vac transformer and get 110 vac. on each side.

How do you wire a 220v three prong to a 220v four prong?
You'll need to contact an electrician who will pull a new wire for you. If you only have 2 wires on the 240 line, you don't have a neutral or a ground; both of which are essential for a modern electric range.
How do I test for a ground wire?
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
Is amp draw on a 220V motor per leg or combined?
Amp draw is always combined. 220V is uncertain if it is three phase or not, because there are both one phase and three phase applications of the 220V motor. In any case, the answer is always "combined".
Two lamps A and B are rated 60W 220V and 100W 220V respectively so why does the answer say that when connected in parallal bulb A is brighter?
In parallel, they both obviously have 220 v across them, so the 100 W bulb is obviously brighter than the 60 W one. The 60 W bulb has more resistance, and in series they both have to pass the same current, so the 60 W has more voltage across it and might be brighter.
How do you tell the hot wire when both are black?
When both wires are black, you can identify the hot wire using a multimeter or a voltage tester. First, ensure the power is turned off at the breaker. Then, turn the power back on and carefully test each wire with the voltage tester; the wire that shows a voltage reading is the hot wire. Alternatively, if you have access to a ground wire, the black wire connected to the ground can be identified as the hot wire, while the other is typically neutral. Always exercise caution and consider consulting a professional if unsure.
How do you wire 240V straight blade outlet when both screws are brass?
Both screws are brass because in the US you need two hots to get 220V. In a 220V only circuit you do not connect the neutral, only two hots and a ground. This is why 220V breakers are twice as wide as 110V and have two terminals instead of one.
Why would a hayward pool pump shut off after 3 minutes?
The most common reason would be LOW VOLTAGE. CHECK THE POWER AT THE MOTOR. MOST PUMPS RUN ON 220V IF ITS ONLY GOT 110 THATS WHY. CHECK THE POWER AT THE TIMER AND BREAKER ALSO USE A VOLT METER AND CHECK THE POWER AT THE MOTOR, BOTH LINES AND NOT TO GROUND.. CHECK THE VOLTAGE AT THE MOTOR..

Will any surge protector work properly in both 110 and 220V?
No, not every surge protector will work properly in both 110 and 220V. Some surge protectors are designed to work with both voltages but others support just one.

Can you use the 220v 50hz appliances in 110v 60hz?
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.
What happens to 220v 50hz personal computer when connected to a 220v 60hz?
Unless the computer has a switch on the back allowing you to use both dual voltages and frequencies, the computers internal clock will run faster.
Can bad credit cause you to fail a back ground check?
No. A criminal backgroud check is completely independent of a credit check. Some employers require both, however.
Why Pontiac Bonneville system monitor on dash not working?
check ground wires under both doors
Do you need a neutral wire for 220v generator?
Quick answer is that 220v does not use or need a neutral. The original concept of the neutral (going back to Edison and DC power) was cutting the power in half (not really accurate but one way to look at it). Think about two 110v batteries in series the neutral would come off the connection between the two batteries. so current flow would go from +110 to -110 (first battery) to +110 to -110 (second battery) resulting in 220 output. The connection between the batteries (the neutral) is +110 / -110 resulting in 0. If you want a 110 current instead of using the full flow you could instead use only 'one side' and the neutral and get the 110. When we made the move from DC to AC the basics of this format was kept. So for 110v you need hot and neutral (and a ground) for 220v you need two hots (no neutral) and a ground.HUGE CATCH - WARNING - WARNING!!!Just because you think your equipment is 220v doesn't mean everything it does it does requires 220v for example: some equipment uses 220v for the motor and 110v for the rest of its electrical needs (Dryers are a typical example). In the old days, the dryer would use the two hots (and ground for safety) for 220v and then use one hot and ground (no 'safety' ground) for 110v. However, people often got shocked because this unsafe method would often cause the entire metal chassis to take on a charge. So todays dryers (and any other machine that has both 220v and 110v components) have and are required to have 2 hots ground and neutral. However, the documentation isn't always specific about the '110v need' and a lot of 220v only equipment will still have 4 wire connections even though the neutral is not needed.If you are sure your equipment never utilizes 110v - then you don't need a neutral (a single motor, no thrills (control panel, laser guides, etc), 220v table saw would be fine with out a neutral (one with the thrills may be fine also - depends on the power requirement of the 'thrills'). I don't know about your generator is depends if it is strictly 220v.
On Silverado 2000 when the lights come on I have one dim And one bright?
check that both bulbs are the same and the connectors are on the same - if they are the same check ground connection
