fork lift battery charger

[Big Jerm]

I went to a call at a building that is being served by a delta 3 phase 4 wire 120v/240v/ 208v high leg. from phase to phase is 240v from C phase to grnd it is 208v then a,b to grnd is 120v.
The call was to hook up a fork lift battery charger (3 phase 208/240/480/600 VAC) that is preset for 480 VAC Star connection. how can I make this work, I have a 3pole 240v breaker and that is the voltage I will use, simply by using the 240 connection but will it work the charger correctly without re tapping the X-fmr for delta connection?

Sounds like you need to change the internal charger taps to match your 240 v system

Along with the charger tranny taps don't forget the control tranny taps.

good point... I think that brings an old "opps" to mind

Just be aware some of the battery charger do have interal fuses which you may have to change as well if they have it inside the charger which I have ran into once a while.

Merci,
