3Phase ASHP - 16a RCBO/ TP

Like the camera, "whose be fiddling in here then?"

In reality it is looking at the door in the far corner, but serves as a "did you monkey with it?" record as well

So far it has been more of the occasional "Doh, I left the lights on!" check after locking up the site, and the resulting trip next day to put them off.

Schnider boards do a lovely "meter add on box" that sits below the DB, it has several advantages,
It bolts directly to the DB, it can act as gland termination lower than the incoming switch which allows easier management of the 25sqmm or 35sqmm tails. It has a sturdy Din rail for mounting meters, RCDs, contactors etc etc and its cheap. Used them for EV RCDs, contactors and metering units for solar.

Thank you.... gonna get on the case today, sounds like a plan ;-)

That is mine!

It sits there as the doors need a screwdriver to open then and it saves going looking for one! Also just out of sight there is a screw in the wall to hand the emergency light test switch and the door keys to the boxes outside for accessing the incoming supply SWA and the (as yet unused) generator terminals.

We are luck that really all staff are "electrically competent", at lest to the point of knowing when not to monkey with something, so locking up it more for neatness and occasional guest loitering than to really keep the usual suspects out.

I used Eaton 3pn C32 & C16 RCBO's on as ASHP project last year and they were about £60ish each from memory.

The N does straddle a way on the bus bar, though, so there's some wastage - they fit better on the Right hand bus than Left as otherwise you also have to mess about with paying attention to wiring them in as the phases get translated which just doesn't look right! [As in - 1,2,3,N at the bottom turns into N(1) 2(2) 3(3) 1(4) at the bottom]
