Intermatic WP3100C – Frequently Asked Questions

1) Will the Intermatic WP3100C in-use cover close with a cord plugged in?
That's what the 2.75 inch depth is for. The WP3100C is an in-use (while-in-use) cover, so the lid shuts over a cord and plug left in the receptacle and keeps the weather seal intact. Standard flip-lid covers only seal when nothing is plugged in, which is why they fail code for anything left connected outdoors. Rule of thumb on the job: check your plug body and the cord bend before you close it, since a heavy transformer-style plug can need more than 2.75 inches of clearance.
2) Does the WP3100C weatherproof cover meet 2020 NEC for a wet location outlet?
Yes. The WP3100C complies with 2020 NEC Article 314.15 for damp and wet locations and carries UL Type 3R, which covers rain, sleet, and ice formation. For an MRO or institutional spec sheet, that is the pairing inspectors look for on an exterior receptacle: Type 3R enclosure protection plus the in-use depth so the opening stays sealed while something is plugged in.
3) What size outlet box does the Intermatic WP3100C fit, and how big is the cover?
Single-gang. The WP3100C mounts to a single-gang box and measures 5.75 inches high by 4 inches wide with a 2.75 inch depth off the wall. Worth measuring before you order if the box sits close to a corner, a door casing, or a siding transition, because the 4 inch width plus that projection is what decides whether the lid swings clear.
4) Does the Intermatic WP3100C fit a GFCI receptacle or only a standard duplex?
Three inserts ship with the cover, giving up to 16 configurations, so it adapts to the common receptacle openings including decorator-style GFCI faces and standard duplex. You pick the insert that matches your device face during install, which is why one part number covers a mixed building instead of stocking a separate cover per device type.
5) Can the WP3100C in-use cover be mounted on a horizontal outlet box?
Both orientations work. The WP3100C mounts vertically or horizontally, so a sideways box on a soffit, deck rail, or under a counter is fine without hunting for a different part number. Handy on retrofits where the existing box was set in whatever orientation the original installer chose.
6) Do I need to buy a gasket or screws with the WP3100C weatherproof cover?
No extra parts. A 1/8 inch neoprene gasket comes pre-adhered with slits for the mounting screws, and the mounting screws plus three inserts are in the box. Press the gasket flat to the wall and snug the screws, don't crank them, or you'll distort the seal you just paid for.
7) Will a clear polycarbonate in-use cover hold up outdoors in sun and hard freeze?
The WP3100C is heavy-duty UV-stabilized polycarbonate, cold-impact tested to -60F, so it resists the yellowing and brittle cracking that kills untreated plastic covers on a south wall or in a northern climate. Clear also lets a property manager or facility tech see whether something is plugged in without opening the lid.
8) What is the exact part number to order for the Intermatic clear single-gang in-use cover?
Intermatic WP3100C. That is the manufacturer part number for the clear, 2.75 inch deep, single-gang in-use weatherproof cover, and it is the one number to quote when standardizing exterior receptacle covers across a property or spec package.
9) Is the WP3100C suitable for pool, spa, and coastal receptacles?
Yes, those are core uses for it. Pool and spa equipment power, landscape lighting, and marine or coastal exterior outlets all sit in wet locations where a cord stays connected, and the WP3100C is built for exactly that: Type 3R protection with the lid closed over the plug, plus UV-stabilized polycarbonate for constant sun exposure.
