How do you perform a continuity check on a piece of three phase cable?

Question

What if the ends of the cable are to far apart for the leads to reach

Answer 1

Because I don't know what your set up is, I will explain what I had to do, when I needed to check the continuity in my power cable from the light switch to the light in the ceiling using my multimeter.

The problem was the two ends of the cable were to far apart for the multimeter to reach. First I turned the main circuit breaker off for the lights.

Next I exposed both ends of the cable though the ceiling and though the wall were the switch was.

Then I used some spare 4 metre long power cable and joined it to the two wires coming out of the ceiling. I set the multimeter to the ohm setting. Now while standing at the light switch I but one probe on the wire at the switch and the other on the extension cable.

For me, it turned out a rat had chewed though one of the wires preventing the light switch from working. Luckily for me I was able to pull new cable though the ceiling and down the wall

Hope what I did is able to help you out.

Answer 2

With a test meter set on continuity, test from end to end of each core, mark the ends with the correct phase colours when continuity is confirmed. Should be very low ohms, depending on length and size of cable.

Answer 3

Go to one end of cable, tie two wires together at that end. Check across them at the other end of cable.
Now do the same with other wires check same way.
