Question: Looking at a 400 amp service disconnect with 400 amp fuses feeding two 200 amp panels via double lugs on the load side of the disconnect. Tap conductors (250 kcmil AL) are about 5' long. Connected load on each panel well below 200 amps. Do the two panel require 200 amp OCPD's? I say yes and quoted 408.36. Other electrician says not due to the 10' tap rule. Who gets the martini?
The other electrician gets the martini.The 10-ft tap rule in 408.36 allows taps to be installed without overcurrent protection at their source. In this case, the taps are 5 ft long, which is less than 10 ft. Therefore, no additional overcurrent protection is required for the panels. Flag for review
