First, determine the primary and secondary current rating of the transformers (see Fig. 1 and Fig. 2 ). For a 45kVA transformer, the primary current would be 45,000VA ÷ (480 × 1.732) = 54A. For the same transformer, the secondary current would be 45,000VA ÷ (208V × 1.732) = 125A. For a 112.5kVA transformer, the primary current …

Some inspectors might insist on bonding bushings, while others may be fine with having the GEC bonded to both the main and the gutter and proper bonding fittings in between. Some inspectors might prohibit running the GEC with other conductors at all per 250.6 (objectionable current). For at least one inspector I worked with, that could have ...For feeders a bonding bushing would never be required when the voltage is less than 250 volts to ground. A service raceway is one that has service conductors in it which would be the conductors on the line side or upstream from the service disconnect. So for example if you had an overhead service down to a meter pan and then a metal nipple … Bonding Bushings. Wherever feeders enter or leave a load center through concentric knockouts, a bonding bushing should usually be installed to ensure electrical continuity of the bonding/equipment grounding system.
