Steel City 664 GP – Frequently Asked Questions
1) What is the Steel City 664 GP, and where does it go?
The 664 GP is a receptacle plate for a floor box, a steel cover plate that carries the receptacle opening at a recessed service floor box. It is sold individually, one plate per order, so order one per outlet position you are covering.
2) What is the difference between the Steel City 664 GP receptacle plate and the Pass & Seymour TM1542 series floor box cover?
The Steel City 664 GP is a steel floor box cover for recessed service applications, sold each. The Pass & Seymour TM1542 series cover is a brass floor box cover and is tamper-resistant, so it is the one to look at when the opening calls for a brass finish surface or tamper-resistant receptacle openings. Both serve the same role as the cover over a floor box, so the choice comes down to the material you want underfoot and whether tamper resistance is required.
3) Can the Wiremold 828MAAP be used in place of a Steel City 664 GP receptacle plate?
They are not interchangeable in purpose. The Steel City 664 GP is a steel receptacle plate for floor boxes in recessed service use, covering power receptacle openings. The Wiremold 828MAAP is a sheet metal audio/video adapter plate for the OmniBox series, intended to carry A/V connectors rather than standard receptacles. If the floor box needs to terminate audio or video, the 828MAAP is the plate for that; for a receptacle opening, stay with the 664 GP.
4) Does the Steel City 664 GP plate come with knockouts for conduit?
No. The 664 GP has zero knockouts. It is a flat receptacle cover plate, not a box body, so all conduit entries are made at the floor box itself.
5) Should I use a steel receptacle plate or a brass floor box cover?
The Steel City 664 GP is steel, which is the normal pick where the plate sits under carpet, tile or a recessed service cover and is not on show. If the plate is exposed in a finished floor and you want a decorative, corrosion-resistant face, a brass cover such as the Pass and Seymour TM1542 Series tamper-resistant floor box brass cover is the alternative. The TM1542 cover is also tamper-resistant, which is worth considering in public spaces.
6) I need to bring audio/video connections up through a floor box, not a power receptacle. Is this the right plate?
No. The 664 GP is a receptacle plate, built around a power receptacle opening. For low-voltage AV terminations in a floor box, use an adapter plate made for it, such as the Wiremold 828MAAP audio/video adapter plate in the OmniBox series.
7) I need a tamper-resistant floor box cover for a school lobby instead of the Steel City 664 GP. What should I specify?
The Pass & Seymour TM1542 series floor box cover is the tamper-resistant option, supplied in brass. The Steel City 664 GP is a steel recessed service floor box cover carrying UL E2969 and is not described as tamper-resistant, so where a facility standard calls for tamper resistance on floor outlets, the TM1542 series cover is the one to put on the submittal.
8) How do I order the right Steel City floor box receptacle plate?
Order by model number: 664 GP, which is also the manufacturer part number. There is a single configuration, so there is no finish or size choice to specify, and it ships one plate per unit.
9) Is the Steel City 664 GP or the Pass & Seymour TM1542 cover a better match for standardizing floor outlets across a building?
Both are floor box covers, so either can be standardized on; they differ in material. The Steel City 664 GP is steel and listed to UL E2969, made in the United States, and sold each. The Pass & Seymour TM1542 series cover is brass and tamper-resistant. Buildings that want a consistent brass trim ring in finished floors tend toward the TM1542 series; where the cover is painted, carpeted over, or in back-of-house areas, the steel 664 GP matches.
