Appleton Contender® factory sealed control stations give you explosionproof push button stations, pilot lights, and selector switches that confine arcing without the labor of field sealing fittings. If you're writing specs for chemical plants, refineries, or corrosive process areas, this episode breaks down exactly how to specify Appleton Contender factory sealed control stations for hazardous areas and match EDS bodies to the right hazard class before the RFP goes out. Ratings matter here: Contender stations carry NEC/CEC Class I, Division 1, Groups C, D; Class I, Division 2, Groups B, C, D; Class II, Division 1 and 2, Groups E, F, G; Class III, with NEMA 3, 7CD, and 9EFG enclosures. Note the gap: this series does NOT cover Class I, Division 1, Group B, so Class I Division 2 pilot lights and push buttons on a Group B application need the EFDB Series instead, not this catalog. Factory sealing eliminates sealing fittings and compound at every conduit entrance, cutting install labor and leak paths. Covers are UL Listed on Contender bodies with an internal ground screw standard. One exception to flag in your specs: tandem bodies still require an external seal within 1.5 meters (5 feet) of each conduit entrance to hold the Class I, Groups C and D rating. Construction is built for corrosive service: malleable iron bodies and covers with triple-coat zinc electroplate, chromate, and epoxy powder coat, plus copperfree aluminum (4/10 of 1% max copper) operators and guards. Contacts are silver cadmium oxide sealed in an isolated phenolic chamber, stainless steel push button shafts ride in stainless bushings, and momentary buttons ship with lockout guards accepting up to a 1/4 inch hasp. Bodies come dead-end (EDS prefix) or feed-thru (EDSC prefix) in 1/2 in., 3/4 in., and 1 in. hubs, 1-gang, 2-gang, 3-device, and tandem configurations. Start here: https://www.pe-energy.com/product/appleton-contender-series-factory-sealed-control-stations-and-pilot-lights/ Pilot lights default to a 120 Vac/Vdc, 50/60 Hz, 6 Watt lamp with jewel colors in amber, opal, clear, blue, and green (suffixes J6, J8, J10, J11, J3). Need LED? Spec EPLLEDR, EPLLEDG, or EPLLEDA at 120 Vac, 10 mA. Running 220, 277, 440, or 550 Vac control power into a 120 Vac lamp? Add transformer suffix S801 through S804. Selector switches run 2 position/2 or 4 circuit and 3 position/2 or 4 circuit maintained contact, with modified spring-return variants at S634, S635, S636, and lockout accessory S349. Pull catalog numbers straight from the lineup: EDS1184 and EDS2184 push button stations (1-gang, dead-end, 10 amp), EDSC2290 feed-thru 4-circuit stations, EFD2868 combination push button/pilot light stations, EDKB102 selector switch assemblies, and EDS11273 3-position selector switches. Torque cover screws to 35 inch pounds and mount nameplate bracket NPBRKT-C0NT between cover screws and cover, never between the ground joint flame path and backbox.
