    Access to Distribution boards

    But should a competent person have access to a MCB/RCBO in the event of an emergency bearing in mind reception is 2 floors below and maintenance is 2 buildings away. What is a reasonable amount of time to wait for a MCB/RCBO to be isolated? There was a fault with a dishwasher that tripped a...

    Access to Distribution boards

    Thanks Vortigern, I'd agree if the whole electrical installation was under the landlords control but the tenent is responsible for the repairs & Inspections. The landlord seems to be responsible for the key & charging for it.

    Harmonics and tripping RCD

    There is a 300mA RCD at the main distribution. I've been told a type B RCD may help. The leakage was measured at 200mA + on start up. The pumps are in a lake where fish and birds are present so I think a RCD is required in this situation.

    Lux Meter

    Hi guys, I'm looking to purchase a lux level meter initially for emergency lighting specification but also for a project involving lactive acid, milk production & cows. Apparently if the light levels are perfect then the cows can produce milk with the correct amount of lactive acid so the feed...

    2 PHASE supply to machine

    Thanks to all for your replies. Thanks to Tony for his Codswallop Award. If I am correct, the reason for this forum is to discuss and help fellow electricians with their day to day work. All I have seen is who's got the biggest phase combination. As for my spelling, I will try and get my teacher...

    2 PHASE supply to machine

    I'm carrying out an EICR to a machine shop ( they make machine guns!). One machine is a sciaky P282 hot riveter. This starts out as a 3 phase, neutral & earth set up at the DB; then terminates in a rotary isolator 30 metres away where it changes to what I assumed was a single phase supply. This...

    underwater lights, SELV, waterproof connectors

    I've been asked to install Zehui Cool White 3 X 3W Led Underwater Spot Light 12V 9W. I'm a bit concerned, firstly, it has a very short lead for an underwater light (200mm), what sort of connector should I use? Secondly, it has a cpc within the flex but there is no continuity between the cpc and...

    Its not that we lose jobs but more that are we losing jobs because businesses are brainwashed into using AC's. I think its the same as a domestic installer per year but an initial £200 to set up
