Hi all,

I know how to check for breaks on short cables from end to end but how would i check for breaks on a long cable ( over 20 metres) using a multimeter?

Thanks

Twist at one end and bell out at the other

I'm not worried....not until i find out if it's connected to anything or not...

Once you test and determine there is a break,the fun can then start, using your meter to measure resistances calculate exactly where along its length that break has occurred

just twist your live and neutral together and do a continuity test between the live and neutral at the other.

Simply check continuity,on each conductor,until you find O/C....then,pull the copper inner conductor,out of the insulation.
Then,measure the length of that copper,and note it down.
Measure the total length of the cable,deduct the length of the copper,and then measure that distance,from the other end.

....This,is where your break is.

then when he's cut the cable at the break, re-insert the copper conductor he's pulled out, and repair. .
