TAYMAC MX4380S – Frequently Asked Questions

1) Will the TayMac MX4380S fit a standard 1-gang outdoor box?
The MX4380S is built for 1-gang box mounting and installs horizontally, so it suits a single-gang exterior box oriented for a horizontal device opening. It will not work on a 2-gang box or on an opening that requires vertical orientation.
2) Can I leave a cord plugged in outdoors with the TayMac MX4380S cover closed?
Yes. It's an in-use cover, so the lid closes over a plugged-in cord and keeps rain, dust, and debris off the device while power stays connected. A self-closing flip-lid cover, by contrast, only protects the receptacle when nothing is plugged in.
3) In-use cover or self-closing flip cover for an outdoor receptacle, which do I need?
If anything stays plugged in (holiday lighting, a pump, a block heater, jobsite power), you need an in-use cover like the TayMac MX4380S, which closes over the cord. If the receptacle is only used occasionally and nothing is left connected, a self-closing weatherproof cover such as the Leviton 7788-CR in glass-filled thermoplastic covers that case instead.
4) What are my alternatives to the TayMac MX4380S if I need a vertical-mount 1-gang weatherproof cover?
The MX4380S mounts horizontally, so it won't serve a vertically oriented device opening. For vertical 1-gang, the Bell Outdoor Comforts vertical decorator weatherproof cover is the option to look at. For a vertical single-receptacle cover sold in bulk, the Mulberry 30552 (BAC1SV) comes in packs of 100.
5) What is the difference between the TayMac MX4380S in-use cover and a self-closing weatherproof cover like the Leviton 7788-CR?
They protect the opening in two different states. The TayMac MX4380S is an in-use cover: it is a 1-gang weatherproof cover with a low-profile in-use housing that stays closed over a cord that remains plugged in, built in aluminum with metallic construction and horizontal mounting. The Leviton 7788-CR is a 1-gang weatherproof self-closing cover in glass-filled thermoplastic, industrial grade, which seals when nothing is plugged in and sits open around the cord while a device is connected. If the receptacle will have a cord left in it outdoors, the in-use style is the one that keeps the opening covered; if the receptacle is only used occasionally, a self-closing lid is the simpler assembly.
6) The box on my wall is mounted vertically. Will the TayMac MX4380S work, or do I need a different cover?
The MX4380S is a horizontal-mount 1-gang cover, so it is intended for a horizontally oriented 1-gang opening. For a vertical 1-gang opening, the Bell Outdoor Comforts 5123 is a 1-gang vertical decorator weatherproof cover and matches that orientation. Note that the Bell 5123 is a decorator-style cover, so it is sized for a decorator/GFCI style device rather than the multi-configurable device layouts the MX4380S accepts.
7) What does the 8-in-1 multi-configurable design on the TayMac MX4380S actually mean for a contractor stocking covers?
One MX4380S housing adapts to multiple device layouts, so a single 1-gang cover on the truck covers several receptacle and switch arrangements instead of carrying a separate cover for each. That is the point of the multi-configurable design: fewer part numbers on the shelf for the same range of openings.
8) Is the TayMac MX4380S metal or plastic?
Aluminum, metallic construction, finished in gray. That matters where a plastic cover would get broken by impact or UV exposure, such as loading docks, equipment yards, and industrial exteriors. If your spec calls for a non-metallic cover, this is the wrong one.
9) Will the TayMac MX4380S cover work on a 4-inch square box with a mud ring?
It's a 1-gang cover, so it mounts to a 1-gang opening. A 4-inch square box needs a 1-gang mud ring to present that opening, or you go to a square cover instead, like the Mulberry 11525 5-inch square weatherproof cover rated 30A.
10) Is the TayMac MX4380S suitable for wet-location outdoor use on a commercial jobsite?
Yes. It's a weatherproof in-use cover from the EXTRA DUTY Series, UL Listed, aluminum, and intended for outdoor and wet-location installs, jobsite power protection, and retrofit work on existing exterior boxes.
11) My outdoor box is a 4-inch square, not a 1-gang. Is the TayMac MX4380S the right cover?
No. The MX4380S is built for a 1-gang box. For a square box, the Mulberry 11525 (CV72R3330R) is a 5-inch square weatherproof cover rated 30A and supplied in packs of 100, which fits that larger square opening instead. Confirm your box dimension before ordering, since a 1-gang cover will not land on a square box's mounting pattern.
12) Is the Mulberry 30552 single receptacle cover a substitute for the TayMac MX4380S?
Not a direct one. The Mulberry 30552 (BAC1SV) is a weatherproof 1-gang single receptacle cover sold in packs of 100, so it is dedicated to one single-receptacle device opening. The TayMac MX4380S is a 1-gang multi-configurable in-use cover with an 8-in-1 design, meaning one housing adapts to a range of device layouts, and its low-profile in-use construction covers a cord that stays plugged in. If every opening on the job is a single receptacle with no cord left connected, the Mulberry is the simpler dedicated cover; if device layouts vary or cords stay in, the MX4380S covers more cases from one part number.
13) Where can I get the manufacturer spec sheet for the TayMac MX4380S?
TayMac publishes a spec sheet for the MX4380S at https://hubbellcdn.com/specsheet/TAYM-MX4380S-SPEC-EN.pdf. Useful if you need to attach documentation to a submittal package.
14) Which 1-gang weatherproof covers are UL Listed if my inspector is asking?
The TayMac MX4380S is UL Listed, and that listing is stated on its own record along with the aluminum Extra Duty Series construction. Among the 1-gang alternatives, the Leviton 7420-YL and Leviton 7788-CR are both specified as industrial grade glass-filled thermoplastic self-closing covers. For any listing marks beyond what each part states, pull the manufacturer spec sheet for the part number you plan to submit.
15) I am buying covers for a whole apartment complex. Which of these comes in bulk packs?
If you are standardizing across many units, the Mulberry 11525 (CV72R3330R) 5-inch square 30A cover and the Mulberry 30552 (BAC1SV) 1-gang single receptacle cover are both supplied in packs of 100. The TayMac MX4380S is ordered as the single MX4380S model and is the one to specify where you need an in-use, low-profile aluminum cover on a horizontal 1-gang box so tenant cords can stay plugged in under a closed lid.
