    Zappi car charger open PEN protection

    Your right to get a low enough resistance on an earth electrode is not likely to happen unless you are next to the transformer. Regulation 722.411.4.1 has a 2 new indents added in the new amendment (iv & v). Which basically says protection is provided by s different device, as long as it...

    Ryefield board

    Not the best picture, its installed in a dark basement with other scruffy services but anyway heres one I'm working on. The small enclosure above the Ryfield houses a SPD. Which is fused from the Ryfield unit. I'm going to add an indicator light to the passive relay on the SPD before its...

    UK Led downlighting goes off when job switched on ?

    Out of interest did you use a V-pro dimmer ? How close is the induction Hob to the dimmer ? It could be the once the Hob is turned on it the noise/ frequency is getting picked up by the dimmer and amplified. I know V-pro dimmers are notorious for going into setup mode which will turn the lights...

    UK Led downlighting goes off when job switched on ?

    It could be a number of things, I'd be checking mis-termination/loose connections at the CU and accessories on all conductors. When you turn the hob on do you lose the neutral or the line at the lights ?

    If a 6kW device in uk takes 26 amps (6000/230), does this mean the same device in the US will take 50 amps(6000/120)?

    Depends if it's a resistive load... In the UK alot of resistive loads have a KW rating but its worked out on using their resistance at the intended voltage. If you take a 3KW kettle in the UK that approximately draws 13amps at 230v the resistance of the element is approx 17 ohms If this were...

    Domestic fuse boards

    Since the new guidance on not being able to use Diversity as a effective method of overcurrent protection on RCCBs what's peoples general view on Split load RCD boards which have 63amp RCCBs ? Do people still use them but just make sure that the mcbs added together protected by the RCD dont...

    Domestic fuse boards

    I believe the official name for these minature RCBOs which claim they are double pole is "single pole switched neutral" as to classed as double pole each pole is identical so overcurrent protection would need to be provided on the neutral conductor too, I think manufacturers like to throw the...

    EICR when not in a scheme.

    Your skilled competent, and have relevant qualitifications. The only thing that can cause problems is some agents request your a member of a CPS and it can be a PITA convincing these people.

    Fusebox consumers units

    I've not fitted one, I've seen one though my local CEF have started sticking them. They looks quite well thought out, knockouts are positioned well and the layout is pretty well thought out.. They do look a little tinny in my opinion, the metal is pressed at the sides, of the CU I dont think it...

    Qualified Electrical Engineer

    It's funny 'Engineer' isnt a protected term but when a job is advertised looking for an electrical engineer then 9 out of 10 times they are looking for someone with some kind of HNC/HND or relevant workbased experience in that field... When a job is advertised looking for a heating engineer...

    "Dumb" Voltage optimisers

    I remember reading the literature for one of these about 10 or so years ago (when they were popular) I convinced that optimisers needed a digital bypass to be complaint. I must have been wrong.

    Recommendations for metal cable fixings

    I would also go for linian think the ones you need for swa are called "Linian super clips" the cost will probably be saved in labour.

    How long you going.

    I finished Friday, we are taking the kids up to Hyde Park Monday, and didn't fancy going in for Christmas Eve. Probably work a couple of days in inbetween as I need to do bit of BNO work for a Restaurant with dwellings above. Nice to know your coming back to a busy new year.

    IR with Di-Log MFT

    I have a dialog. When the screen turns red its usually because voltage is detected on the circuit. Mine has never said fuse though.. They are quite sensitive meters and will pick up capacitive inductance while carrying out IR testing, I just leave my probes on until the voltage disappears...
