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.
Why not hook ground to neutral since they are hooked on same spot in breaker box why not in outlet box.?
The "hot" wire and the neutral wire both carry current (the same amount, in fact) when a load is connected to complete the circuit. The ground wire never carries current except when a fault-to-ground situation occurs. Yes, neutral and ground wires should both be at ground potential, but NO they should not be connected at the outlet.
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.
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.

check ground wires under both doors
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.
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
Do you have 220v or 110v?
An ipod nano is 110 volts. Why, because our regular outlets are 120 volts AC.
