Critical feedback request - Consumer unit.

[MrShine94]

Hello, Please can I have some feedback on the quality of a fuse board I installed recently. I am fairly new to consumer unit installs. Newly qualified.

Looks neat,not sure of the actual workings of the system.
Where’s the bottom main switch fed from.

 

[Cid]

Looks very good

 

[Midwest]

Does look good, be prepared to be ripped apart though

Have you used ferrules on your RCBO fly leads?

Have you used ferrules on your RCBO fly leads?

I'm presuming you only need to add ferrules if you shorten the lead, or do you guys add them anyway?

 

[telectrix]

only thing i can fault is the bunch of cables coming in top left.some vertical plastic trunking would look better. otherwise a very neat job.

Looks like the SWA is a 4 or 5 core.

What is the deal on that big bunch of T+E exiting to the left? Have any applicable grouping factors been applied to the cables or is that not how they will be on the day? In an installation like this it is usually impossible to load them all heavily due to the limited total supply, but if some are run near their limit this can overcook them a little.

You've got nice long service loops on the L & N, not sure whether there is the same on the CPCs. I always like to make sure there are a few inches spare for re-termination by taking them across the board and back or around in a curve.

Can't see the armoured termination which is often a variable in an otherwise good install.

I know few people do this on a domestic install but I always number the cables with the appropriate DB way, to avoid frustration if multiple cables are taken out duing an EICR.

But yes, generally pretty smart.

Yes that is true the bottom main switch is for the off peak supply feeding storage heater and immersion

No none of the boards have ferrules I understand that is a requirement but my foreman will not listen.

We are installing 200 of these board in a council estate. The cables on the left are being boarded .

If the flylead is fine-stranded and has been cut and terminated in a terminal that is not designed for fine-stranded cable, then that is a genuine defect in the work. Bring your own ferrules or leave the full length of the flylead so you can terminate using the original crimped / spotwelded end.

Thanks for your reply I agree with what you are saying. I have previously uploaded a past board from this job and received the same feedback. My foreman is refusing to purchase ferrules does not think they are needed.

show him reg. 526.9. ( from 17th . 18th. may be different number.).

 

[Baddegg]

Don’t fret, neatness comes with experience

They don't look like they have them, so guess they've been shortened.

Edit, op's replies just bee added.

No, same number in 18th.

 

[Dustydazzler]

Nice job

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

 

[Martin Kerr]

You need to colour identify you bottom neutral

Top and bottom on the same phase?
Could do with sleeving the incomers.
