    Glue Guns Failing earth continuity test

    I will ask the maintenance electricians to get a picture in the morning as they are planning on replacing the wire (again) Thanks Nick 1571928886 That's a great idea. I think it might me a self tap screw and ring terminal. But I'm sure we could do something similar to what you suggest to stop...

    Glue Guns Failing earth continuity test

    Hi Guys Long time since I last posted but I have a problem I'm stuck on. My company uses a few industrial hand held glue guns. We have been experiencing repeated problems where the glue gun is failing on the earth continuity test. (Full test every 3 months) Typically 0.26 - 0.56 ohms. We...

    Choosing the right size cable

    I appreciate that and your advice hence why im trying to get an better understanding on best practices. Its just the contradictions I come across which confuse me. For instance with the 110v equipment like drills and grinders they are sometimes fitted with cable suitable for the load only and...

    Choosing the right size cable

    Ok that makes sense apart from we have have no 16A outlets on the shop floor. The place is slowly being upgraded a bit at a time but I don't think I will be getting and 16A sockets in the near future.

    Choosing the right size cable

    Choosing the right size cable

    He's a very experienced electrician who I have alot of respect for I guess what he's getting at is that providing the cable is big enough to carry 32A under fault conditions the breaker would trip before the cable melted

    Choosing the right size cable

    How do you know there will be no risk of overload? I can understand a motor may be worked too hard and draw more than the FLC but this wouldn't apply to everthing

    Choosing the right size cable

    Haha thanks guys. The problem is I can't change the size of the MCB in the distribution board which will be rated at the full 32A as the sockets are used by all and sundry on the shop floor for all sorts of applications tool use etc. Thats what he says, the cable should be capable of carrying...

    Choosing the right size cable

    Hope someone can clear something up for me. I've been selecting cable recently to wire up industrial machinery for test purposes only. I usually purchase H07RN-F or H07BN4-F. My boss has informed me that the cable needs to have a current carrying capacity to match the supply it's being being...

    Pat testing cable size

    Ok so you basically do the same as me. What about the plug, would you be happy to fit a 32A plug, providing the csa of the cable is large enough to carry the design current of the appliance, but not necessarily 32A.
