Thomas & Betts E989NNR – Frequently Asked Questions
1) Is the Thomas & Betts E989NNR junction box made for PVC conduit runs or do I need a metallic box?
It's a non-metallic PVC box built for rigid non-metallic conduit, so it belongs on a PVC conduit run where you solvent-weld or use PVC fittings into the box. If your raceway is EMT or rigid steel, use a metallic box and fittings instead; mixing a non-metallic box into a metal raceway means you also have to deal with bonding continuity through the box, which a PVC box can't provide.
2) Is this PVC junction box UL listed for commercial electrical work?
Yes. The Thomas & Betts E989NNR carries UL listing under file E11461, which is the reference an inspector or spec reviewer will want on a non-metallic junction box for commercial or institutional work.
3) If I run a PVC box, how do I carry the equipment ground through it?
A non-metallic box has no metal path, so the equipment grounding conductor has to be carried through and spliced inside the box. Every PVC conduit run needs that separate EGC pulled with the circuit conductors; the box itself is not part of the ground path.
4) What size is the E989NNR box and is it big enough for splicing several conductors?
The box is 4 x 4 x 6 inches, which gives real depth for splices rather than the shallow profile of a device box. That volume is aimed at pull points and wire splicing where multiple conduits land in one enclosure. Fill still has to be figured per code for the number and size of conductors you're landing.
5) Will a PVC box like this hold up in a damp or corrosive area where steel boxes rust out?
PVC is the usual answer to corrosion. Non-metallic construction means there's nothing to rust, which is why these get used in wash-down areas, parking structures, agricultural buildings and near chemicals where a steel box would pit. It's the same reason PVC conduit gets specified in those spaces.
6) What's the exact part number to order, and does it come one box at a time or in a case?
Order Thomas & Betts model E989NNR. Selling unit is each, so one quantity equals one box. Covers, conduit adapters or terminal hardware are separate items.
7) Can I use the E989NNR as a pull box where several conduits come together?
That's one of its intended uses. It's catalogued for conduit junction points, panel connections and splices, and the 6 inch dimension gives room to bend and dress conductors at a pull point. Pull box sizing rules based on the largest raceway still govern how big a box you're allowed to use for angle or straight pulls.
