    ELCB or RCD for instant tankless shower water heaters?

    Some electric tankless shower water heaters have inbuilt ELCB. Are they better than Triton water heaters which don't have it ? and does Triton tankless water heaters have any inbuilt security? Or an external RCD is better ?

    4293 elcb coding __________

    Been called to a job for a second opinion, Previous spark said current db set up would warrant a code 2 and therefore need a board change. Granted the elcb set up isn't great for discrimination but cant see this warranting more than a C3. But what about the elcb itself? It Tests out fine. Any...

    1 amp CO ELCB

    Came across what I'm pretty sure was a current operated Crabtree ELCB today. Just had a search on here and a google and haven't found a lot. Annoyingly I didn't take a picture as I thought they would be more common than they evidently are! Pretty sure its the first I've seen in the 15 years I've...

    Problem with very occasional ELCB trippage

    Hi all My problem is that my CU is about 30 years old. It is the grey metal "wylex?) one with the main incomer switch on the right (ELCB) with the little yellow test button above it. The original rewireable carts have been replaced with MCBs. The problem is that occasionally ,maybe 2 or 3...

    Current operated ELCB

    What is the most sensitive current-operated ELCB that I can buy for fitting in a domestic single-phase system? Is it less than 30mA, and if so where from?

    Voltage elcb

    anyone got a recomendation for this, (usual case not wanting to spend) swap an existing socket for fcu for new boiler, no bonding to gas/water against regs but velcb on tt so installing bonding could render the elcb useless making the install worse than what it is. so two options: swap socket...

    ELCB confusion

    Hi, Completing an EICR on a local authority property. The main switch is an MK 'Earth Leakage Circuit Breaker' rated 60amp 30ma. Of course it's not a true ELCB its actually an RCD or current sensing device, see: ln5760 | eBay for an example. My question is I cant see a BS number on it, does...

    ELCB testers- is it worth getting one?

    Hi. Am new to this forum and just wondered if anyone had any tips about ELCBs and their testers. It seems that there are still many of these obsolete ELCBs still in use (in my area of Weardale Co Durham) and I've read about the testers for them tripping out other properties in the same location...

    Questions about a shared supply. A fault next door trips my ELCB.

    The semi-detached house next to mine is being refurbished, including rewiring work. Our electricity meters, fuseboxes etc are back-to-back on the party wall. My ELCB has tripped a few times recently, and I eventually realised that it happens when someone is working next door. Last time it...
