whats it feeding

Drying ovens via Ring Main pulls about 20 amps per phase

 

[Marvo]

Are the drying ovens single phase?

 

[pomem]

The majority are single phase, there is an intention to install a 3 phase oven at a later date fed by a 16 amp switched commando from the same board.

yep
its actually an option on mem panel boards.

Yes, it'll generally be an option on most premium manufactures DB's. Virtually all our 3 phase plant room DB's have MCCB's as the main isolation switch. Most of them featuring ground fault, along with other adjustable protection facilities....
