    2core swa, not earth load end.. TT

    Hi, Been to a job with a 2core swa supplying the garage.. The swa has been glanded inside house to CU. But the other end in the Garage has had the swa run in plastic conduit with no gland on the swa so unable to test r1/r2. However the garage has its own earth rod. So technically the swa is...

    LED lights from dimmer flickering. Load is below dimmers minimum rating.

    Hello. So I've learned a lot about dimmers on this last job. The customer wanted everything downstairs on dimmers and boy has it been a learning curve. I've split a lighting circuit and the customer has asked for 2 x st64 led bulbs on pendants to be put on a dimmer. The problem is they're...

    Load Testing

    Hi, ive been asked to carry out Load testing on a whole shop to see if the existing supply cable can take more load, now I'm familiar with working out loadings with the on site guide, but the conversation I had led me to believe this can be measured with a clamp meter, surely this way is not...

    Smallest possible cable for a 4w LED load.

    Hi All, This is a bit niche but i've been asked to refurb an antique lamp to dimmable led and i'm after a very tiny cable that will take 230v but only run a single 4W LED. There are 5 of these on the lamp that come back to a connector then off in 0.75 flex. Also after an inline dimmer for the...

    Load and heat

    Hello. New to this forum stuff so hopefully this makes sense. I've recently installed a 10mm 3core cable (H07FN-R) to power a 12kw electric boiler. On full power the boiler is drawing 46Amps. I'm a bit concerned as the cable is omitting a slight heat when drawing this load, was just wondering if...
