Silicon insulated test cable by the roll?

whjohnson

Those of you who make up your own test leads, where do you buy your cable from? Am thinking of knocking up a R2 wander lead with 30 metres of 4.00mm on a home made roll/holder. Thing is; I can only find lengths limited to 10 metres. Since a kewtech ready-made item costs nearly £100 I'm sure I can make something up for less than half that and which is superior.

Comments welcome.

    I feel that some of us are over thinking what should be a simple matter.

    For brief testing use at a voltage that might be very briefly full mains voltage, but that is normally insignificant, I would use any common type of mains voltage wire. Probably tri rated. Remember that brief tests are not the same as being part of an installation.

    This all depends on where and why you are carrying out the tests.

    At one end of the scale is experiment at home, or perhaps at a stretch on a workshop bench, where, as you say, a quick test using a single insulated cable may be OK.

    Towards the other end of the scale is a test on-site where anything might happen, or if you are an employer where these days I'd not like to run the risk of not using the right tools for the job, just in case anything goes awry, given EAWR. Then you consider the larger the turnover of an organisation, the larger the fine … 

    We need to remember that this Forum is read by people working across the scale.

     

    I got the impression someone wanted to make a specific test lead arrangement, perhaps to use from time-to-time at work, and given that impression, I wouldn't want to use single-insulated.
