Arlington Industries 454 – Frequently Asked Questions
1) What size ground wire can I land in the lay-in lug on the Arlington 454 bushing?
The lug takes 14 AWG at the small end and 2 AWG at the large end, so anything from a #14 equipment ground up to a #2 bonding jumper lands directly. If your grounding electrode conductor is larger than #2, this bushing's lug will not accept it.
2) Can I use aluminum bonding wire in this Arlington grounding bushing, or does it have to be copper?
Either. The 454 carries a dual copper/aluminum rating on its lug, so an aluminum bonding jumper is acceptable in the same connector a copper one is, within the 14 to 2 AWG range.
3) Is the Arlington 454 bushing UL listed for an inspected commercial job?
It carries both UL and CSA listings, which covers inspections on either side of the border. Country of origin is the United States.
4) How much room do I need inside the panel for a 1-1/2 inch Arlington 454 grounding bushing?
Plan on 2.184 inches across and 3.130 inches on the height dimension, which includes the lug body sticking out past the conduit. In a tight gutter or a crowded wireway that extra height is what decides whether the bushing clears the adjacent raceway, so measure before you commit the knockout.
5) Why use an insulated grounding bushing instead of a plain plastic bushing on a conduit end?
A plastic bushing only protects the conductor insulation from the cut conduit thread. The Arlington 454 does both jobs: it is a metal bushing with an insulated throat to protect the wire, plus a lay-in lug so you can bond the raceway back to the enclosure with a 14 to 2 AWG jumper. If the run needs a bonding jumper, whether for a service raceway or a high-voltage feeder, a plain bushing will not satisfy it.
6) Will a zinc grounding bushing hold up in a damp mechanical room or parking garage?
Zinc is the body material, which gives corrosion resistance for indoor commercial, light industrial, and service panel work. For continuously wet or chemically aggressive locations, confirm the environment against your spec rather than assuming an indoor-rated bushing carries over.
