Thomas & Betts AJ-2 – Frequently Asked Questions

1) Will the Thomas & Betts AJ-2 ground clamp fit a 2 inch water pipe?
Yes. The AJ-2 clamps pipe from 1-1/2 to 2 inches, so a 2 inch water service is at the top of its range. Anything smaller than 1-1/2 inch or larger than 2 inch needs a different size in the family.
2) What size grounding electrode conductor can I land in this water pipe ground clamp?
The wire range is 6 through 250, so it takes anything from a #6 grounding electrode conductor up to 250 kcmil. That covers typical residential service grounds through large commercial services on one clamp.
3) Is the AJ-2 ground clamp UL listed for grounding electrode connections?
Yes, the Thomas & Betts AJ-2 is UL Listed, which is what an inspector looks for on a grounding electrode conductor connection to a metal water service.
4) Can I use an aluminum ground clamp on a copper water pipe?
The AJ-2 body is aluminum with a tin plated finish. The tin plating is what makes it acceptable against copper pipe, since it keeps bare aluminum off the copper and resists corrosion at the joint. Clean the pipe down to bright metal before you set the clamp.
5) What size wrench or socket do I need to install this ground clamp?
Two fasteners. The aluminum wire screw takes an 11/16-20 socket, and the clamp screw is a 5/16-18 steel screw. Bring a socket for the conductor screw and a driver for the clamp screw and you can set it in one pass.
6) How much room do I need around the pipe to install this clamp?
The clamp measures A = 3-7/8 inches and B = 3-3/4 inches. Allow that much clearance around the water service before you commit to a spot, especially where the pipe runs tight to a wall or close to the meter.
7) Can this ground clamp be used outdoors or in a damp crawlspace?
The tin plating over the aluminum body is there for corrosion resistance, and the description calls it suitable for indoor and outdoor electrical installations. Water services in crawlspaces and at exterior meters are the normal use for a waterpipe style clamp like this.
8) Is the AJ-2 ground clamp sold individually or only in a box?
It is sold each. For stocking a truck or a shop, the inner pack is 10 and the outer carton is 50.
9) Is this Thomas & Betts ground clamp RoHS compliant for a spec job?
Yes, the AJ-2 is RoHS compliant, which covers most institutional and government submittal requirements on material content.
