Sizing cable for forklift

Former Community Member
Former Community Member
Hi all, charger plate has following info;

230vac single phase

Rated at 44amps


Cable length will be 5 meters and method to be clip direct. 


I'm thinking of using a 45amp rcbo, and a 4mm swa which gives me 49amps if clipped direct. 


The thing that's putting me off is that the charger comes with a pre installed tail which looks like a 10 mm conductor size have I missed something here?

    I would be inclined to use a 50 amp MCB and cable to suit.

    For a long hour load, I feel that a 45 amp MCB is cutting it too fine for a nameplate load of 44 amps.


    If the charger is an electronic type then it will draw more amps at low input volts. At 207 volts I would expect an input of about 48/49 amps.


    If the charger is a classic copper/iron type, then at 253 volts I would also expect an increased current draw.
