Small transformer better than over sized? - 11/12/13 04:58 PM
The load calculated for a (480X208) transformer for multifamily using the optional method (220.84)is significantly smaller than the load calculated using the regular method. It is close but it would allow a smaller transformer (750 vs. 1000).
Are there any disadvantages going with the smaller size?
The advantages are smaller physical size and heat output.
