    open PEN protection.

    Would any fellow electricians consider using an open PEN device to protect a metal trailer used as a "Canteen". It is likely to be often connected to TNCS (forbidden by 717.411.4) and placed on concrete which makes the use of TT and rod impossible. I can draw similarity to an EV charge point...

    UK Issues with Fusebox AFDDs anyone???

    That's intersting to hear. I met a Lewden rep at a show and he told me about the Fusebox recall. He said Lewden AFDDs had no problem because they were all tested in the UK and not China.

    Shepherds Hut, which regs?

    Thank you for your reply Brian, I think I will go with conventional regs (not part 7);.

    Shepherds Hut, which regs?

    They have wheels. The wheels are only for positioning to a fixed site (solid steel, no tyres). I understand it is a planning regs "get-out", that's the only reason they have wheels at all. Thank you for taking the time to answer.

    Shepherds Hut, which regs?

I am leaning towards a "Park Home" which is not a Special Installation I believe. There are parts of section 7 which could also be applied, caravan, mobile home...

I think it is this discharge that has just enough power to kick - in the timer...

    LED Lamps and extractor fan problems..

    I was just searching for a resolution to a similar problem. Changed some filament lamps in a Bathroom yesterday to LED. Customer messaged this morning to say the fan has been running all night and keeping her awake. I am going back today to fit a "snubber" across the feed and switch line. Same...

    Dual rcd board

    Hi Mike, I would be interested in your view on the type A type AC RCD situation. NICEIC seem reluctant to comment. NAPIT say potentially dangerous (in the main). What do you think please ? There can't be many places with just resistive loads and no electronics (for DC interference).

    Dual rcd board
