pop noise whilst testing!

[andy1984]

im an apprentice electrician and was doing some loop testing and some fault current testing yesterday.

when doing this testing where my probes were on the circuit there was a crack/pop noise at the end of the test(just before i got the reading).

the electrician didnt know what it was when i asked him, anyone know what the noise is down to?

was it on a lighting circuit

 

[andy1984]

it was on a 3 phase board not a lighting circuit.

just wondered if there was any danger or reason for the noise?

It sound like a bad / dirty connection between your test lead, and the earth of the circuit you were testing.

When carrying out an EFLI test your tester allows a current to flow to earth, and it is probably the current flow making a connection that made the pop sound (If that makes sense)

Have you ever connected / seen a live wire connected to a load, and heard the crackle and seen the spark? This is a similar occourence.

You don't work with this bloke do you?

It didn't sound like any of these, did it?

would put it down to a bad connection aswell. ive had this before myself on 'dirty' terminals.

its even pitted / marked the end of my test probes before

always press on firmly and contact a point that is 'clean'.


......well its either that or the beans!
