Default 18 th edition metal consumer unit

I've been a spark for 30 years and 17th qualified with 2391 and from the installation contracting background, but for the last 5,6 years I've been an maintenance electrician at a local hospital, and never had to replace a consumer unit since the plastic ones were allowed
So a friend has asked me to upgrade his plastic non rcd fuse board
So I'll be putting in a dual rcd metal consumer unit as I should I realise I have to get a special gland for the tails, but for the incoming cables in the back of the board can you seal the hole needed with intrimuscent fire sealant what do you guys do, and for entries into the box I hear blind grommets are sufficient is this true
Thanks

First let me translate your Engish

I've been an Electrician for 30 years, and 17th qualified with 2391 I was 17th in my class, with about 2,391 installs.

"but for the last 5,6 years I've been an maintenance electrician at a local hospital, and never had to replace a consumer unit since the plastic ones were allowed" What kind of consumer unit are we talking about ?

"So a friend has asked me to upgrade his plastic non rcd fuse board" Is this an electrical panel with fuses ?

"So I'll be putting in a dual rcd metal consumer unit as I should I realise I have to get a special gland for the tails", WTH ?

but for the incoming cables in the back of the board can you seal the hole needed with intrimuscent fire sealant what do you guys do, and for entries into the box I hear blind grommets are sufficient is this true Photos , especially the gland ?

They use to use plastic fuse boxes but now they have to be changed out for metal breaker panel with a main rcd (like a gfci but reacts at a higher threshold, I think, to lazy to google).

Tail i presume is the wire you put in the box. As most homes are brick you flush mount and the cable goes in the top of the box or the back.

I think he needs to find a Uk based website.

Yeah, yank out the old box, slam in an all-in-one combo panel, a couple of Romex conns., maybe some duct-seal, and bobs your uncle.

I thought this was posted in the uk section, as uk sparks will know what I'm talking about
Thanks for help anyway
17th refers to 17th edition of the wiring regulation
Tails and double insulated cabling coming from the meter to the consumer unit
I suppose I'll post this on a UK website

We speak the same language, but it's completely different

Had a employee from Ireland, and he called a homerun a ringloop

Yer they don't use homeruns as everything is a ring main. Start at the breaker run a loop then return to the same breaker.

Had to re-learn a lot of stuff when i came to Florida.
