    Anyone use a concrete nailer?

    have been thinking of getting one of these, as things like fitting capping, conduit etc would be much easier/faster. I dont really know much about these, and am yet to find anyone else with one to try, so wondering if anyone has one, and what are they like? Do they consistantly bury the nail...

    SDS drill being used instead of core drill?

    What is the actual difference between a core drill and a SDS with a clutch? Other than price. I just use a mains SDS and have had no issues.

    Stroma Certification Scheme Stroma is it possible to fail assessment

    I was partly responsible for an Niceic domestic spark being booted recently! The customer called me up asking me to take a look at a Re-wire just done, it was truly awful and dangerous. I emailed the pics to the NICEIC, asking them to contact the customer. Apparently the Niceic inspector said...

    What cabling system do you prefer in commercial/industrial environment?

    All the wiring will be behind the stud wall inside the partition, then the light fittings themselves inside a recess with sealed glass on top, So both the light fittings and wiring are sealed from the actual spray area. As far as I'm aware the wiring behind the stud wall does not need any...

    Thanks Guys, Sorry about delay coming back, all been a bit busy!!! Yes i would say from what I've measured with a clamp they are drawing around 100-120A/PH most of the day during business hours. Each phase is almost exactly the same, as its 90% 3PH equipment (no neutral). I have tried...

    1361-2 overload blow, time How long?

    Guys, Just to settle a debate i had earlier with another spark. 100A 1361-2 DNO fuse, constant current of 130A. He thinks it will blow within minuets. I think it will last a good few hours. (At least). I cant find any time/current info on 1361 fuses, but would quite like to know the answer...

    What would cause earth short in 3PH motor?

    Sorry, i probably wasnt very clear. I put clamp meter on earth and started, it showed 40A before MCB tripped. I then noticed continuity on my voltage meter between L1(U1) and earth, so then disconnected the motor. I then used the IR tester to double check the cable between the started and...

    L1- U1/W2 L2- V1/U2 L3- W1/V2 Which i believe to be correct, and used this before. But even if i got a coil mixed up would it cause an earth to coil short?
