The facility I work for has utility feeds off the same substation. The A feed comes off a 12.5kv to 480 padmount transformer 3 phase wye with a neutral to our main A switchgear . The B feed comes off a similar transformer in a straight delta configuration with no neutral to the main B switchgear.
My interpretation of 250.24 tells me I should have a neutral on the B side to return fault current back to the source. Downstream all of the B loads eventually pass through a transformer and pick up neutrals. However the service transformer, B switchgear and supporting 3meg generator fo not have neutrals.
Is this code compliant or am I misinterpreting something?
