Bonding for grounding bushing req.

[velezl]

The service is a 1200a with 4 metal chase nipple with grounding bushing. Which bonding wire size is required for the bushing?

 

[raider1]

Are the chase nipples located on the line or load side of the service disconnecting means?

For bonding jumpers installed on the line side check out 250.102(C) and for bonding jumpers installed on the load side of the service disconnecting means check out 250.102(D).

I might add, IF they are on the line side of the disconnecting means, the size will vary depending on your running a separate bonding jumper to each bushing or looping one conductor thru all four.
Can you give us more detail ?
