What do you mean not amendment 3 compliant? It's a metal enclosure, with metal door, metal hinges and metal catches....what else do you want? You just choose what catch/lock you want when you order it? Same with the Ryefield that Buzz linked to earlier.

The supplies.

Can't see the point of spending money on a DB with straight through links, the Henley block could be sat ontop of the steel trunking which is slotted to accept the enclosed tails would look tidy enough.

Supply is 25mm,

Agreed Henley would achieve exactly the same, I just think DB would look more like it was designed that way from outset. Henley just looks like an after thought.
But I agree getting 5 no. SWA into DB might be a struggle, I'll need to consider bigger board if I go this route.

Bus bar chamber and switch fuses...it's fit for purpose and designed for the job. Out of meter into a 100A switch disconnector, into bus bar chamber, length of trunking slotted sat on top with paxolin between, bush switch fuses on to trunking, link bus bar chamber and switch fuses with singles in the trunking, gland SWA's into the switch fuses...Job done.

Door needs to remain closed when not in use so needs to be top hung. A lock is not sufficient apparently! Had this conversation with Hager today.
Seems crazy to me, but they are the regs as I understand them.

How on earth can you say that’s not amendment 3 compliant? It’s a proper metal clad industrial fuseboard with a sealed, screwed shut door, they contain fires much better than the thin little ‘domestic’ boards!

Well you've understood wrong then. There is no regulation stating door must be top hung and whoever told you such is talking out their arse.

Much better solution, I like it.

The door must be self closing, that's the important bit.

Well it constantly in use as the electricity will always be flowing through it whilst the installation is live!
Show me where in the regulations it says it must be top hung? And if that’s the case then what about the ‘amd3 cu’s’ that don’t have a self closing lid??

If it’s that much of an issue to you then get a busbar and switchfuse setup, square d do a modular busbar chamber with space for 6 switchfuses which come with pre-manufactured connecting links.

You better tell Schneider that their eazy 9 consumer units don’t comply then.
