Galvanized bonding

[ptonsparky]

I have a galvanized casing that needs to be bonded. Manure sump pit. Cad weld only or is there another option. SS bolts maybe?

Above ground or below for the connection?

Drill and Tap a hole and use servit post?

Below ground.

Why do you have to bond it?

Below ground.

Hmm. Cald weld might be the best bet, I’m not sure if you could find a servit post listed for direct burial.

Well looks like it is listed for direct burial.

Thanks. Just got to the shop computer to search this out.

I would consider it a a well casing.
It is for a submersible pump that will transfer feedlot run off to another pit for eventual distribution to a pivot

I don't think it is a well. It won't hurt anything to bond it but I don't think it is a well casing.

Maybe qualifies as a local metal underground structure (250.52 (A)(7)).

I am not even sure it qualifies as being underground.

What makes a world of difference in tapping is a tap tool that will allow a 3/8”ratchet to work. Than get a 3/8” adaptor for your impact drill and use it.

I usually just take it in a few threads at a time than reverse it and repeat depending on the strength and depth of the metal I am working on.

On the well columns I have bonded, I have a 3/8 bolt welded to the column. Then attach a lug. For this I would use a ss bolt
