Appleton ECC753RH – Frequently Asked Questions

1) What hazardous location classifications is the Appleton ECC cord connector approved for?
The ECC Series factory sealed cord connector covers Class I, Division 1 and 2, Groups B, C and D; Class II, Division 1 and 2, Group G; and Class III. Enclosure ratings are NEMA 7BCD and 9G, and the housing is watertight. That combination is what lets it go into a Group B (hydrogen) area as well as combustible dust and fiber locations without a separate seal, since it is factory sealed.
2) What size cord will the Appleton ECC connector accept?
It takes No. 18 through 12 AWG 3-conductor Type S or SO portable cord. The plug side is built for a specific cable outside diameter range, offered as .250 to .375, .375 to .500, or .500 to .625 inch, so measure the jacket OD on the cord you are using and pick the matching range. A cord outside the range you order will not clamp or seal correctly.
3) What nipple size do I need to mount this Appleton explosionproof cord connector to my enclosure?
The ECC connector mounts through a threaded nipple in either 1/2 inch or 3/4 inch to match the hub or opening on the fixed enclosure. Check the enclosure's tapped hub before ordering; the two sizes are not interchangeable without a reducer or adapter.
4) Do I have to add a conduit seal after this connector?
No. The ECC is a factory sealed device, so the seal is built into the fitting at the point where it enters the explosionproof housing. You still need to follow your area classification drawings for seals elsewhere in the run, but no separate sealing fitting is required at the connector itself.
5) How does the Appleton ECC connector land inside the enclosure, and do I need to supply pigtails?
Leads come with it. Appleton furnishes 12 inch leads of #12 stranded wire on the connector for splicing to the wiring or equipment inside the explosionproof housing, so you wire-nut or terminal-block to those rather than landing on screws in the fitting.
6) Is a 20A 480V explosionproof cord connector the right choice for permanent equipment, or should I hard-wire it?
A cord connector like the ECC is for equipment that needs limited or short-range mobility, where the load has to be disconnected and moved without breaking conduit. If the equipment never moves, hard piping into the enclosure with rigid conduit and a sealing fitting is the simpler install. The ECC is rated 20 amps at 480 Vac, so it covers small motors, portable lighting, mixers and similar loads within that limit.
7) Will this connector hold up in a corrosive plant environment, like a refinery or wastewater area?
The body is copperfree aluminum, limited to 4/10 of 1 percent copper, with an epoxy powder coat finish. Copperfree aluminum is the standard specification for hazardous locations where acetylene or corrosive atmospheres rule out copper alloys, and the epoxy coat adds corrosion resistance. The watertight construction also means washdown and outdoor exposure are within its rating.
8) What is the exact part number for the Appleton ECC explosionproof cord connector?
The model is Appleton ECC753RH, a 20 amp, 480 Vac factory sealed portable cord connector in the ECC Series. Use that designation when matching a replacement on an existing installation, since the ECC family varies by nipple size and cable diameter range and the suffix is what pins down the configuration.
