I m qouting a tanning bed salon in which 8 tanning beds will are to opperate on 235 volt delta. Supply voltage will be 208/120 three phase with a delivery voltage of 214
Two buck boost as an autotransformer have a rating of 123.9K 312 load amps are capable of boosting 208 to 229 with a 450 amp fuse size.
Loads based on 235 three phase
5 16 amp 6,512 32,560
2 32 amp 13,024 24,048
1 56 amp 22,792 22,792
79,400 total load
With an imput load of 215 amps @ 214 and a secondary load of 195 @ 235
Using 450.4 Would the proper wiring method be
300 amp primary fuse on 4/0 copper terminating into a 225 amp main breaker 24 circuit panel, within 25 feet. With individual overcurrent devices and branch circuits to feed each bed.
I know this would be at best the minimum requirment. Looking forward to your suggestions
