Bonding Bushings


I am adding a sub-panel next to the main outdoor panel and I was wondering if I had to put bonding bushings inside of each panel on both ends of the rigid nipple.

Re: Bonding Bushings


Would you need the bonding bushings if the sub panel was 50' away? 150?
Same applies to 4" away.

Well the distance is irrelevant, I know I need the bonding bushings, just wanted to make sure I needed one on both sides. Where is Magnettica when you need him? lol

why do I need a sub-panel? because the electrician that wired the house filled the main panel to its full capacity and then added twin breakers at the bottom. There is absolutely no room for anymore circuits plus the cover is hard to get on. A sub-panel should have been installed from day 1

Re: Bonding Bushings


it does need to be bonded, it does not require a bonding bushing on either end of nipple.

Thanks dmanola7, it's nice to be respected by your peers.

As to answering your question, you only need to bond the nipple once.

250.96 Bonding Other Enclosures.
(A) General. Metal raceways, cable trays, cable armor, cable
sheath, enclosures, frames, fittings, and other metal non–
current-carrying parts that are to serve as grounding conduc-
tors, with or without the use of supplementary equipment
grounding conductors, shall be effectively bonded where nec-
essary to ensure electrical continuity and the capacity to con-
duct safely any fault current likely to be imposed on them.
Any nonconductive paint, enamel, or similar coating shall be
removed at threads, contact points, and contact surfaces or be
connected by means of fittings designed so as to make such
removal unnecessary.

this does not make the use of a bonding bushing mandatory

You're right, you could use a uh, now I can't remember what it's called instead of the bonding bushing.

Thanks Magnettica, from now on your the man Im gonna run to for the CORRECT answers. These other jacklegs have probably never picked up a codebook in their life. (No offense to the jacklegs out there) I myself live by the code so its refreshing to have my questions answered with a code quote. Keep up the good work Magnettica!!

There's more than a few knowledgeable electricians around here other than me. But thanks.

It's always good to give a code reference.

Re: Bonding Bushings


By the way... do you have to use the RIDGID nipple? Because if you can use PVC you never have to worry about bonding it. Just a thought.

I would imagine I have been reading and using the code book since before you were born. Perhaps if you would actually open and read the book instead of just picking it up you could learn a bit more. Or you could just keep looking for someone to give you the answer.
