I was wondering what is the maximum limit of sub-panels that can be installed from a sub-panel that is fed from a main panelboard?
the sub-panel has a main as well as the main panelboard. the first sub-panel is protected on the supply side by a 100A two pole.
the voltage is 120/208.
i want to install a 100 amp sub panel from a 200A sub-panel that is fed from a 200A main panelboard, that also has a 200A main.
i want to use 3 #4 in a 1" emt, using the emt as the egc.
i will place a 100A main in my subpanel.
is this legal? what about 408.16 (A)?
thanks for any replies.
