Critical feedback request - Consumer unit.

[Wilko]

Good on you for asking .
Re the bottom row - out of habit I put the isolator on the end. As you've shortened the RCBO N lead, these can't easily be moved now. And yes, if you are going to shorten that N lead it needs to be ferruled. If there's room (seems plenty here) I would use the RCBO as they're supplied.

Nice job

Why is there a piece of cardboard wedged down the back of the consumer unit ? Packing to get level ?

No that is the tub strap box used for fixing the SWA

You need to colour identify you bottom neutral

Yes your right thanks for the advice

The only thing that looks a bit suspect is the fact that they are Proteus.

Nice looking job, good to see when someone takes pride in the end result. Agree with all the other comments and will add; don't forget to fill those gaping cable entry holes (the top one's going to be a bitch) with intumescent seal or equivalent fire stop especially as the unit is mounted on a wooden backboard.

Can't be arsed with arguing, but where does that ---- come from?

17th Edition Amendment 3, 421.1.201 (ii)
states that consumer units shall be enclosed ...etc.

You can hardly call the CU enclosed if there's a gapping big hole in the back, especially as it's pointing at an easily combustable material such as wood.

The intent of that reg is to ensure the fire containment of the enclosure is maintained, which it isn't with a big hole in the back facing wood. It would be fine if it was mounted on a non-combustable wall, but it's not.

Think about it, what's the point of having metal enclosures, metal self closing doors over the mcbs, having to fit non combustable blanks, all designed to keep a fire within the CU, then a big hole that a fire can escape out the back of?

A couple of intumescent pillows stuffed in the holes will suffice.

I'm freshly back.

Reg 421.1.201, item (ii) refers to using a enclosure made from combustible material to be installed in a cabinet or enclosure made from non combustible material, i.e. comply with (i) or (ii).

Unless they have changed the reg again in the 18th (I only have the BYB), there is no requirement to use intumescent seals in a CU made from non combustible material, only to maintain the IP ratings as per reg 416.2.1 (BYB). I don't believe the back of a CU requires this rating, although if someone could access the back, it would make common sense to maintain a similar IP rating.

Don’t fret, neatness comes with experience

It takes a real expert to do a messy install though ;o)))))

Does look good, be prepared to be ripped apart though

The breakers are leaning slightly to the right ;o))))
