In regards to tap rules I have a job where I'm arguing with the engineer that I'm right what say u guys here's the details
Plans say to run a riser to each floor into a splice box , from that splice box pipe into a MLO panel
I say OCPD is needed the engineer is arguing 240.21 (b)
I'm arguing 240.21 (B) (1) (1) states specificly the tap conductors do not extend beyond the switchboard paddleboard disconnecting means or control devices they Supply so if you were to use the actual panel board as the splice box fine no OCPD nneeded
once you leave that enclosure in my opinion 240.21 (B) (1) (1) is out the window and protection is needed weather or not it's 10' or less
240.21(b) (2)(2) says the tap conductors terminate in a single circuit breaker or single set of fuses that limit the load to the ampacity of the tap conductors this device shall be permitted to supply any number of additional overcurrent devices on his load side
Am I seeing this wrong? Who agrees or disagrees
