    Does a CU swap require a full initial verification on all circuits before it can be energised?

    The C3 was a 70-90mm gap between the existing conduit and the board. Planned to be sorted with boxing in later and grommets. Risk assessment done expected very low risk from the position of the board. Could not physically cause or contribute to an accident short of sticking a fork in it.

    Unless he inspected and tested. Which he could have done. But didn't. (I still find no regulation supporting your view mind.)

    Surely that is referring to the design process.

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    Ah, right. The electrician refused to do the testing based on the C3. Said it failed outright. Periodic inspection and testing every 12 months. I admit it's a weird one. Just my own pondering whether the installer could have given permission to energize.

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    Lol no. Just want people's opinions. I'd have tested it, but failing that I think I would have put on one circuit at a time. Until it was all up. There's nothing definite in the regs. Just wondered what the popular consensus was... while I also have a beer.

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    That's what I'm saying though. It's just a board change. There aren't really any tests that are anything to do with the wiring up of the board itself. A visual could confirm that live, neutral and earth cables were in the correct terminals or if there was damage to cables. Tork screwdriver for...

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    As far as I can tell mistakes on both sides. Electrician thought 6-8 hours to install and test. Had to put in extra metal conduit for fire alarm because board had to be moved further left to align the conduit. Board supplied had incomer on wrong side and most CPD's supplied were wrong too. True...

    Ok... maximum security prison. Various high risk prisoners topping themselves and stabbing each other... yes planning should have been way way better... but loss of power was a real H&S risk. Refusing to test it or put it back on for 2 days over a C3 fault? The more I think about it the more I...

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    Agree. Conduits line up perfectly. There's about a 9-10mm gap. It's boxed in with no stress or strain & no access. Essentially the conduit is rendered null & void?

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    The reason given for not doing anything was there was a C3 fault. The board installed was smaller than the original so conduit no longer fitted. (Not installers choice) it was planned to be boxed in. This was predicted and reported to management. Knockouts were given grommet strip edging...

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    That was my thinking, system had periodic inspections and the initial verification. Job was planned by the bosses, timing and planning not up to the electrician. Advice to next shift on at 8am to test critical systems given. Client happy to wait a further 4 hours. They neither tested nor...

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    Ok, To explain the situation... it's 4am, The electrician has been working since 8am. Beginning the testing process will be dangerous as the electrician is too tired to continue. The CU is installed properly so won't go bang an inspection of the CU shows this. If it is not energised there are...

    Does a CU swap require a full initial verification on all circuits before it can be energised?

    To my understanding it would be ideal to test and inspect before energisation, but it isn't 100% necessary. If it leaves a client without power, it breaches health and safety (no power to safety services etc) or inconveniences them I'd have thought it would be reasonably practicable to turn on...

    LOL been asking around for 3 years. I don't want to sit and watch the tumbleweed rolling by that empty thread either. I'll post you all pictures when it's done.
