# You asked: Should transformers have ground continuity?

## Do transformers have continuity?

Transformer Continuity Test

A continuity test tells you whether there’s a break in either of the coil wires. To conduct this test, the transformer must be completely disconnected, and you need to set the multimeter to read resistance in ohms (Ω).

## Should there be continuity between ground and neutral?

The ground and the neutral are connect together at the main panel. Continuity between them should be present. If it was open then you would have a problem.

## Should hot to ground have continuity?

It’s either continuity through loads or you have the hot/neutral backwards. You should have continuity from neutral to ground.

## How do you test a transformer with an ohmmeter?

To test your transformer, simply touch the red and black pins of your ohmmeter to the opposite ends of the transformer’s wiring. Read the display and compare the resistance on your ohmmeter to the resistance stated on the transformer’s data sheet. This is sometimes listed on the transformer’s enclosure.

## How do you know if a transformer is good or bad?

You can do a quick test for each winding for an open while the transformer is still connected in a circuit. Assuming you’re using a cheap inaccurate ohm meter. Look for a reading of somewhere between one and about 10 ohms. If any winding reads higher than 10 ohms you have probably found a bad transformer.

## Should I have continuity between hot and neutral on a transformer?

There should not be any continuity between the primary and the secondary on a normal transformer. Raw resistance only gives a rough idea of the viability of a transformer…the real measure is inductance, but that takes other tools to measure.

## How do you know if neutral and ground are bonded?

First check for voltage between the neutral and ground bar. If the voltage is more than a few millivolts you probably don’t have a bond but zero volts doesn’t mean you are bonded.

## What is the resistance between ground and neutral?

@lal • 02 Jun, 2013 Ideally the resistance between earth and neutral should be zero.

## What happens if neutral touches ground?

The neutral is always referenced to ground at one, and ONLY one, point. If you touch the neutral to ground anywhere else, you will create the aforementioned ground loop because the grounding system and the nuetral conductor are now wired in parallel, so they now carry equal magnitudes of current.

## Should I have continuity between phases?

Each phase to phase must have a continuity if winding is OK. If any particular phase fails the continuity test, your motor is probably burnt.

## Should black and white wire have continuity?

Both of the switch loop wires (white with black tape and the black wire from the same cable) should not be connected to anything, have their ends taped individually, and curled up in the box out of the way.
