Commercial Fryer

32a -everything,  mcb, isolator, sockets and plugs, 4mm radial,

 

[Sidewinder]

Do all the calcs add up for 4mm radial & at the last socket on the line etc.?

Personally I would not use 4mm sq for 32A.

 

[tom1]

runs 4m max will the terminal on these socket take 6mm in and out

 

[Sidewinder]

I don't know Tom, it will depend on the socket.

They are generally designed for being on independent radials.

 

[tom1]

will look at the sockets when I get them, see what there like and  run them on separate radials if need be

thanks

will the terminal on these socket take 6mm in and out

unlikely. ive got 2x 4mm in some before but even that is tight

 

[tom1]

two or 3 radials seems to be best option

 

[Sidewinder]

So, if you are going for a radial per socket, do they need to be 32A.

What is the rating of the devices?...

 

[Andy™]

individual radials with 16a mcb / outlets is best option

if the total load of 2 is less than 20a, then you could put a 20a radial with 2x 16a outlets

As this is a commericial catering establishment. I would assume the supply is three phase.

As the OP wants to put all three units on one circuit (I am assuming they are next to one another). Then I'd put forward the suggestion of one 16A ceeform socket on each phase of a 16A three phase circuit. SWA into adaptable box, few DIN rail terminals with links installed for the neutrals and earths then out to three adjacent interlocked SPN 16A sockets

Done similar arrangements with site cabins when distance was an issue and needed to be eccomical as possible with cable sizing

 

[Andy™]

but if you have 3 individual SP circuits on a TP MCB then your not minimizing inconvenience incase of a fault...

3 of these would prob be straight forward install, they can replace the fryers in future for anything up to 16a

only concern I mentioned before was they could site the units under the isolation point

This issue would be covered by PUWER98, in which case it is doubtful that those sockets would be suitable as emergency means of isolation of energy anyway, so, something else would be required by statute law.
