    Installation above suspended ceiling issues

    You could use a load of Hager J501 boxes, flex out of them to the lights, or put clix in. Use all round band to fix to the ceiling and conduit boxes to fix the clix to. I've seen worse.

    Help with 3 phase star delta motor

    It is all starting to make sense. I'm assuming T in the diagram is the sequence timer? There's only one trip light on the panel so I guess they're both linked through the two contactors. It's hard to tell if the motor moves in high speed due to the fact the control panel is about 20 metres...

    Help with 3 phase star delta motor

    The wiring diagram is attached to the original message. The top picture. Ah no I haven't, what reading would I expect? I assumed that it was star delta so then assumed that the windings should be okay. Assumptions being the mother of all f**k ups! My bad. Yes, so C1 low speed would run, the...

    Thanks for the great video. Apologies. I have little experience with motors in general.

    Help with 3 phase star delta motor

    Hi, I've been sent on a job to investigate a fan not working correctly. After investigation found that the fan doesn't run in 'Auto' or 'High speed' and just shows 'trip' on the control panel. The fan will run in low speed. I've replaced the belts on the fan as they were frayed. Opened the...

    BS5266 Emergency lighting

    Because the Lux level might not be the same as to when it was installed? We are talking about installations that are 10+ years old. Aren't there specific requirements of Lux levels in escape routes etc? Apparently there is a specific course for this kinda thing. I'd be interested if anyone is...

    BS5266 Emergency lighting

    Afternoon guys, Just a quick question in regards to annual inspection and testing of emergency lighting as per BS5266. A supervisor at work has asked us as engineers to carry out a load of 3hour annual discharge inspections on various sites and a few engineers have refused to do this. This is...

    LED PIR Flood Light wiring

    I swear time guard had a flood light with an extra PIR output too for connecting another light to it. So it was SW/F in, SW out, N, E. Just another thought.

    Couldn't get his head around it.

    JCC tricked my apprentice!

    Right hand side. Sorry the picture isn't the best nor my description He obviously connected as per the instruction on the fitting. Not knowing that the earth terminal is screwed to the metal base

    JCC tricked my apprentice!

    Glad he wasn't holding the metal gear tray whilst checking!

    The mystery of the intermittent fault on flourescent light

    Tad overkill for the one light? Remember that this bloke is connected to the steel structure on a metal ladder and (within our firm) has to maintain three points of contact on said ladder. Throw a loop test into the mix and a RCD protected circuit then we're in for a show!

    JCC tricked my apprentice!

    As the subject suggests JCC threw in a curveball in a 5ft LED light that completely stumped my apprentice. The back story goes like this. We are on a small commercial job, cushy number installing 40 LED IP rated emergency and non emergency fittings. I gave the task of telling my third year...

    EICR coding................

    I'd go for a C3 as you've already said. If I had this in a commercial premises I would put a label on the outlet to notify for 'particular use only' for example. Just incase Mr. Bodger comes along and Spurs off it.

    The mystery of the intermittent fault on flourescent light

    Replace the ballast. 6ft will have a PC2/70W and a 5 foot will have a PC2/58W. Some of the bigger wholesalers stock them too. Would be easier to do that off your ladder than the whole fitting! If it's non EM might be worth putting LED tubes instead. Less to go wrong.

    Electrical certificate for own house

    When you are certificating a job you are forwarding information to the specific governing body to then be compiled and forwarded to building control. A certificate is then generated. Just simply signing a certificate isn't going to notify them obviously. You'll either have to pay the BC direct...
