I've got a job where I need to move a DB, it's currently in a pub kitchen getting covered in grease etc and the location is right above hot surfaces, not an ideal place.

The plan is to install new circuits in the kitchen, food prep and storeroom fed from a new DB in the storeroom. this will be fed from the exiting DB supply. Supply is from BS88 gG 63 amp single phase fused isolator at the intake.

My plan is to install a suitable JB which the pyro gland will be terminated into then use 16mm T&E to extend roughly 3m to the new board location. JB size 150x150.

As expected the pyro has tested fine but I forgot the measure the conductor size before turning back on and now can't get a shutdown until I can do the board move in a couple of months time.

Cable size looks similar to 7/064. The JB and joints can be made accessible so screw connections can be used.

I remember someone posting a link for some what can only be described as baby Henley blocks that would be ideal for this but I cannot remember their name and my Google Fu is failing me today.

So what options do I have?

Can you access the glands...the size will be on them.

Sounds like an adaptable box for jointing, as said.

I'm going with weatherproof purely down to the amount of grease generated in the kitchen, it's small and has two deep fat fryers running most of the day. Typical fried pub grub.

My main headache is jointing the cables.

I could just be lazy and install a rotary isolator... I will now go away and slap myself for suggesting that.

Edit: Why didn't I think of this before, DIN rail in the box with a couple of neutral connector blocks...

I'd still go with galv adaptable box with din rail. We use them regular in kitchens...totally flat surface and overlapping lid, with an isolator nearby, out of the way of the mess.
Nothing wrong with an isolator, if it suits....maybe a decent one.

Galv box would be easier for terminating the earths.

This is my first kitchen job so I want to get it right first time as this will lead in for more business.

Get yourself a pair of non slip boots.
One of the kitchen hands was in there last week with a two foot scraper on the hot plate cleaning the crap off, very very rank... 🤮

With the pyro, yes, but you've got din rail for earth term.
Good luck with the kitchen work.

The cable size will be on the gland, no need for a shut down.

If your talking 16mm... that pyro might be a bit solid, too.....I think a bit bigger than a 6''x 6'' box would make it easier. Terms will take up a fair bit of space.

What about a suitably sized IP65 Metal Enclosure, something like this;

Bit more nicer looking, and hopefully keep the fat at bay. Lockable as well.

Look at Rs components, they have some nice stainless steel enclosures that would suit the application
