[Rosco]

What are you intending to use in your garage to use 58A?

Lots of heat lamps and extraction equipment by the sounds of it

 

[LankyWill]

You need a 35mm 4 core

No there are not. Design load of maximum 58A that means 13.34KW. OCPD 60947-3 probably 80amp as main switch (in the house) and then RCDo 63amp in mcb in garage.

By my calculations 10mm would be better. Correct?

I didn’t think 60947-3 related to OCPDs, but I may be wrong.

Do you mean you are intending to use an 80A OCPD? In which case I don’t think 10mm will be suitable, off the top of my head 16mm may be better.

Lol probably. But not sure. Customer request.

 

[buzzlightyear]

Idealy 2core SWA as only one phase needed. IS 6mm

only one single phase. or sub mains .

 

[Peter Hahn]

Hum ...... then shouldn't you know this? and unless you are a member of a CPS its still an issue..

Well done that is the topic

 

[Peter Hahn]

Quite a worrying response here. OCPD for the garage supply is the house CU main switch ?

As you are a new member could you state what qualification and experience you have, or pop it on your profile and set your profile to be able to be viewed publicly. This will help us help you best.

No it is not.
