Power Requirements

Power Requirements

3 phase electrical supply (Mains or Generator) 415 volt
A 32amp 5 pin female socket (industrial) rated IP44, must be provided from a 32amp 3 phase motor rated MCB type Cor D. The electrical supply to the silo must be backed up by a 30mA RCD, which is exclusively for silo use. Fuse protection to be 50Hz.
The socket is to be provided within 5 metres of the silo.

Single phase electrical supply (Mains or Generator) 240 volt 

A 32amp 3 pin female socket (industrial) rated to IP44 must be provided from a 32amp motor rated MCB type C or D. The electrical supply to the silo must be backed up by a 30mA RCD, which is exclusively for silo use. Fuse protection to be 50Hz.

The socket is to be provided within 5 metres of the silo.

Please note that where two or more silos are in use on a site independently, a separate socket is required for each silo, e.g. where a natural mortar is being used internally on blockwork and coloured mortar is being used externally on brickwork both at the same time.

Generators
If using either 3 phase or single phase generators, the unit must have a minimum capacity of 12kva (per silo - if two or more silos are being used at the same time).
