    Interesting problem

    Hi Marconi, sorry but what is the use of checking the IR of the other circuits? One FCU supplies a wall heater, the other has nothing on it.

    Interesting problem

    Hi Marconi, thanks for your comments. I happened to have another MEMshield RCBO in my van that day so I swapped it over and still same effect. All the other circuits are on RCBO's, all wired in T+E. Its a small circuit only 2 x 2g sockets and 2 x FCU's, and yes i removed the load conductors...

    Interesting problem

    RCBO trips immediately after connecting both legs of the ring. Figures are 0.12MOhm. On a TNCS 3P Supply. Oh and MEMshield 2 C Type RCBO.

    Interesting problem

    Nothing plugged in, that was my suggestion on the phone when the client first rang me. Oh and yes neutral fly-lead + earth lead removed whilst testing. With either side of the ring connected to the RCBO (in turn) will operate fine. When both all are connected, RCBO trips. I had all the sockets...

    Interesting problem

    I was called out to look at an RCBO tripping that powers a ring final circuit in a youth cafe. Checked the IR values at the DB - and all >299. I removed the conductors from the RCBO and checked just that circuit. Now weirdly, when I go to one of the sockets and test either way, the value for L-E...

    Gu10 led

    Using megaman 3.5w, no dimmers involved. Tightened everything right up as well.

    Gu10 led

    Hi everybody. Had a few issues with GU10 LED's (3.5W), seem to dim or flicker. Does anyone know of any circumstances that can cause this? My wholesalers assure me that 'mine are the first to be returned', which I doubt! A bit concerned as I have installed hundreds of these, or the 5w...

    Plastic inserts for flush back boxes

    Thanks, but that wasn't what I was thinking of. They are like a foldable thing, that you can cut down to size with a stanley.

    Plastic inserts for flush back boxes

    Hi guys, saw a product advertised in professional electrician a while ago but can't remember the name. It was a plastic device to clip to the back of back boxes so that those pesky plasterers don't plaster your back boxes over or not reach anywhere near them - as like what happened to me on a...

    Voltage Stabiliser

    Even before the PV's were installed, the voltage was pretty high. The machines have 3P motors, and the control gear is 24V. Would the 24V PSU be affected by the incoming voltage fluctuating?

    Voltage Stabiliser

    Exactly Dave! I can count on one hand the times I've measured 230V at source!

    Voltage Stabiliser

    Sorry guys zoned out for a few days.. From memory the manuals for the machines specify 220-230V.

    Voltage Stabiliser

    Looking to use the Marshall Tufflex ones. What would you recommend? Thanks.

    Voltage Stabiliser

    Looking to condition 2 D.B's which supply some box manufacturing machines (designed for european voltage). There are 2 large P.V. arrays further down stream which make the voltage fluctuate. Voltage at the origin is typically at +240V.

    Voltage Stabiliser

    Hi all, do any of you have any experience of voltage stabilisers? Can they be fitted on sub-mains, or do they need to be at the origin? Thanks in advance

    FCU and Led under-counter light problem

    To Geordie Spark: I had this problem with an FCU before, admittedly an LAP one. So thought it would be prudent to take a replacement with me and just swap it. The FCU in question this time is a BG one, which are usually alright. Had no end of trouble with LAP bits in the past, so will not use...

    Are you saying that there is a charge being stored somewhere then?

    FCU and Led under-counter light problem

    Hi all, having a problem on a job... Using a switched FCU to control some LED under-cabinet strip lights. Customer reported that the lights were staying on after the FCU had been switched off. So I thought the FCU must be stuck in on position, so I replaced the unit. Had a call from the customer...
