cable problems

[potatoman]

Hi ,how do you check the resistance of a cable thats about 140m long, goes through 3 consumer units and between the consumer units it is different sizes

 

[telectrix]

measure each section and addd up.

 

[potatoman]

can I use a ohm meter

 

[trev]

What options have you got?

 

[telectrix]

can I use a ohm meter

be better than using a gas meter.

 

[potatoman]

What options could I have

 

[trev]

None mate I was having a little giggle at your expense. Please accept my apology

With the greatest respect, are you the best person to be measuring a cable 140m long through 3 CUs?

 

[ackbarthestar]

Lol,.... However, the way this thread's heading a Gas meter well may be more appropriate.

 

[potatoman]

How about answering the question

 

[telectrix]

more to the point, why need to know?

 

[micknew]

Best answer is employ a trained sparks IMHO mate.

thought i did in post#2. measure the resistance of each section, the add them up. low ohm meter, then a pencil and paper ( or , if you are flush, a calculator.)

 

[micknew]

Seems like he might be trying to work out volt drop.

Use a low resistance ohmmeter and a zeroed (very) long lead to measure the resistance of each section and add the resistances together.


If you have more than one of the same size conductor connect the conductors together at one end and measure the resistance between the two conductors at the other end and halve the result to get the resistance of one conductor.
