Thomas & Betts E381D-CAR – Frequently Asked Questions

1) Can I use the Thomas & Betts E381D-CAR weatherproof T-box with NM or non-metallic sheathed cable systems?
Yes. The E381D-CAR is built for non-metallic wiring systems, and the box itself is non-metallic rather than die-cast. That also means no corrosion at the box on coastal or wash-down exteriors, and no bonding of the enclosure to worry about the way a metal box requires.
2) Is the E381D-CAR a single gang box, and does it come with a cover?
One gang, and the cover is included with it. So for a single outdoor device or a splice point you are not sourcing a separate cover plate.
3) Will the E381D-CAR weatherproof box accept a lamp holder for an exterior flood or yard light?
Yes, it is compatible with Red Dot lamp holders, which is what makes it usable as a mounting point for exterior lighting rather than just an outlet or junction point.
4) I need more than one device at an outdoor location. Is the E381D-CAR the wrong box?
It is, if you need two or three devices at one point. The E381D-CAR is a one-gang enclosure. For a two-gang outdoor box, the Pass & Seymour WPB Series two-gang in die-cast aluminum covers it; for three devices, the Mulberry 30601 Royal Mountie is a three-gang die-cast aluminum weatherproof box. Both of those are metal, so they take a different wiring method than the non-metallic T-box.
5) What is the closest single-gang weatherproof box to the Thomas & Betts E381D-CAR if I want a deeper box?
The Thomas & Betts E381D-CAR is a single gang weatherproof box in gray non-metallic construction. If you need more wiring volume behind the device, the Pass & Seymour WPBD series weatherproof one gang deep box is also gray and also a one-gang weatherproof box, but it is built as a deep box, giving more room for conductors and device wiring in the same single-gang opening.
6) Do I have to buy the Thomas & Betts E381D-CAR T-box in a case quantity?
It is sold each, but the order multiple is 10, with 10 to an outer package. Plan the count in tens, which usually suits a multi-unit or new-construction job better than a single replacement.
7) Is the Thomas & Betts E381D-CAR RoHS compliant for a government or institutional spec?
Yes, the E381D-CAR is listed as RoHS compliant, which covers the restricted-substance line item that shows up on most public and institutional submittals.
8) Where would I use the Thomas & Betts T-box instead of a die-cast aluminum weatherproof box?
Use the non-metallic T-box where the wiring method is non-metallic and corrosion is the concern, pool and spa surrounds, coastal exteriors, agricultural and wash-down walls. Go with a die-cast aluminum box like the Pass & Seymour WPB Series or Mulberry Royal Mountie where you want the mechanical toughness of metal or the circuit is run in metallic raceway.
9) For a facility standardizing on gray weatherproof boxes, how do the Thomas & Betts E381D-CAR and Pass & Seymour WPBD compare?
Both are gray single-gang weatherproof boxes, so they match visually across a run of exterior devices. The E381D-CAR is non-metallic and ships with its cover, and it is RoHS compliant. The Pass & Seymour WPBD is the deep-box version of a one gang weatherproof enclosure in gray. Standardizing on one or the other mainly comes down to whether you want a non-metallic body or the extra depth.
10) What color is the Thomas & Betts E381D-CAR, and will it look right on a residential exterior?
Gray, uncoated and unpainted out of the box. Gray reads neutral against stucco, concrete, and most siding, which is why it is the common choice on exterior walls where a bronze or white metal box would stand out.
