ECN Forum Forums Code Related Discussion NEC & other Code issues Autotransformer OCPD location

Thanks, guys.

Charlie,
I follow you on the 2-wire secondary.
Although my '02 NEC is in the truck, the '99 Handbook shows an example(figure 210.8) of a buck-boost providing 240 from a 208 system and there is fusing shown on both sides of the autotransformer ?!
