3-phase cooker circuit installation

[hightower]

would SWA look too out of place?

Yeah, white walls, black SWA, wouldn't be the prettiest.

Well if the important factor in the design is cheapness then why not just chuck in a bit of flex in sticky back trunking?

Wind it in a bit mate, you asked me a question with regards to a certain issue you highlighted. I responded saying that heat fluctuation isn't going to be an issue. Tell you what mate, I'll just start lashing in 25mm armour everywhere shall I, since anybody that wants to save a quid or two must be cutting corners.

I've worked in many commercial kitchen environments. Rotary isolators are always used for cookers/steamers within this environment.

Id stick a 25mm or 32mm gland out the bottom of the rotary isolator if you need to keep the price down a socket arrangement being forward thinking may be nice but If its brand new cooker the likelyhood of any imminent reason to unplug itnis probably small

@hightower ,

When I did my first 3 phase job, I had a chat with my wholesaler regarding sockets and isolators. They had some nice looking combined units that included mechanical interlock so they couldn't be turned on unless the socket was properly connected.

If memory serves, they worked out slightly cheaper than a separate isolator and socket, and if you felt the need to go all the way and provide RCD protection, they had add on sections to accomodate a 3 phase RCD.

Just a thought

hightower has gone quiet. customer has just informed him that it's a gas cooker.

 

[hightower]

Sorry, not quiet on purpose, just it's Friday night, the beer is flowing, and I'm drowning in Sunderland's tears. I've taken everything on board and my installation will be a hybrid of your suggestions based on what I think we'll work best and limiting cost within reason.

I'm struggling to find 5-core 6mm H07, any suggestions?

 

[suffolkspark]

Leave the cable on the cooker was supplied with?

 

[suffolkspark]

Allthough i just stuck it in google and it was available from multiple sites?

 

[hightower]

The cooker doesn't come with a cable. Would SY be a suitable cable for the 2m length from cooker to commando plug?

Cable - https://www.10outof10.co.uk/acatalog/Cable.html

 

[suffolkspark]

SY isnt heat proof is it? Literally bang 6mm 5 core HO7 in google and theres loads of places, edwardes is ok ive used them before... You might only need 4mm anyway check the CCC of it

 

[hightower]

Sorry, when i said I was struggling to find somewhere stocking it I meant local. It's a bit strange I've got to order from a website I've never come across before, but if needs must...

 

[davesparks]

If you want local just get it from your local wholesaler, they’ll be able to get a cut length from their preferred cable supplier.
I assume they will as my local wholesaler never has any issue getting cut lengths of cable, the last one was 10m of 35mm H07-RNF single core

That must have been a big cooker !
