Eaton 2887-BOX – Frequently Asked Questions

1) Will the Eaton 2887-BOX connector fit a 12/3 SJOOW cord?
Yes. The 2887-BOX accepts #18-12 AWG conductors and grips cord jackets from 0.25 to 0.63 inch in diameter, which covers 12/3 SJOOW and most lighter portable cordage. If your cord jacket measures over 0.63 inch, the clamp will not close on it properly and you need a larger-bodied connector.
2) Is the Eaton 2887-BOX a plug or a female cord end?
It is the female end. A 5-15R is a receptacle configuration, so the 2887-BOX is the connector body you put on the load end of an extension cord or cord set to accept a standard 15A, 125V plug. If you need the male end that goes into the wall, you want a 5-15P plug cap instead.
3) Can I use this Eaton connector on a 20 amp circuit or with 20A equipment?
The 2887-BOX is rated 15A at 125V only. It can sit on a 20A branch circuit the way any 15A device does, but it will not accept a 20A (5-20P) plug with the sideways blade, and it must not be used to terminate a cord feeding a 20A load. For that, specify a 5-20R connector body.
4) How do the wires land in the Eaton 2887-BOX, screw terminals or push-in?
Back wire with screws. Conductors land under clamping screws inside the body rather than wrapping a binding head, which is faster to assemble in the field and holds stranded cord conductors securely. Standard hand tools are all you need, no crimper.
5) Is this connector tough enough for a jobsite extension cord that gets dragged around?
The body is armored vinyl over brass contacts, which is the construction used for commercial and light-industrial cord sets that get repeated handling. The yellow housing also makes the cord end easy to spot on a floor or in a pile of cordage, which is part of why contractors spec this color for temp power and tool cords.
6) Will the Eaton 2887-BOX ground my portable equipment properly?
Yes, it is a two-pole, three-wire grounding device, so the equipment grounding conductor in your cord lands on its own terminal and carries through to the ground pin of whatever plug is inserted. You must use three-conductor cord; a two-wire SPT cord has no ground to land.
7) Can I use this to replace a damaged cord end on an existing extension cord?
That is one of its main uses. Cut back the damaged end, strip the conductors, and land #18 through #12 AWG under the back wire screws. The 2887-BOX replaces the female end only. If the male cap is the damaged one, you need a 5-15P plug to match.
8) Will a standard household plug fit the Eaton 2887-BOX?
Yes. A 5-15R accepts the ordinary three-prong 125V grounding plug found on virtually all North American tools, lamps, and appliances up to 15 amps. It will not accept twist-lock plugs or any 240V configuration.
9) What is the exact Eaton part number to order this yellow 15A connector body?
Order Eaton 2887-BOX. That is the manufacturer part number for the yellow 5-15R, 15A, 125V armored vinyl connector body with back wire screw terminals.
