364-12 Required Busway used as feeder must have O.P.

System Service 208/120 Y 3 phase 4000 Amp M.B.

I would like to use the 25’ Tap Rule - Sec 240.21 [C] feeding a 800A Brk

with 1/3 the 4000 A/1332A, 3 set 700 KCMIL X 3 = 1380 Amp – 4" EMT/ 4-700 Kcmil.

Bonding by the EMT Metal Conduit – Sec. 250.118

I want to feed from load side of 4000 Amp M.C.B. to a SwitchBoard that contains (RD1700A Frame) Trip A.

1 – 800 Amp AL Main Structure

2 – 800 Amp AL Commercial Metering Structures

6 – Left Socket is Totalizer & Right Socket is general

Each structures is 3 tenants, total of 2-would be 6 tenants. Each with a 200 A CB for future Office Tenants.
