Crouse-Hinds EDSC271 – Frequently Asked Questions

1) What is the difference between the Dead End and Through Feed Crouse-Hinds EDS back boxes?
It comes down to how the conduit runs. The Dead End boxes (EDS171, EDS271, EDS371) terminate the run at the box. The Through Feed boxes (EDSC171, EDSC271, EDSC371) let the conduit pass through and continue to the next device, so you pick Through Feed when the station sits mid-run and Dead End when it is the last point on the circuit. Both are single-gang FlexStation EDS back boxes in the same Feraloy iron alloy body.
2) What conduit trade sizes does the Crouse-Hinds FlexStation EDS single-gang back box come in?
Three: 1/2 inch, 3/4 inch, and 1 inch. Each size is available in both the Dead End and Through Feed configuration, so a 3/4 inch run mid-circuit takes the EDSC271 and the same run terminating takes the EDS271. Match the hub size to the rigid conduit already stubbed to the location; you cannot bush this box down to a smaller trade size and keep the explosion-proof rating intact.
3) Can I use this explosion-proof back box in a Class I Division 1 area?
Yes. The FlexStation EDS back box carries a Class I, Division 1 NEC hazardous rating, which is the rating for locations where flammable gas or vapor is expected to be present in normal operation. That is what puts it in refineries, paint and solvent storage, and process areas rather than a Division 2 boundary zone. It is built to NEC/CEC standards.
4) Does the Crouse-Hinds EDS back box come with the switch or cover?
The EDS is the back box only, the enclosure body that mounts to the conduit and houses the device. The operator, the cover, and the device itself are ordered separately from the FlexStation EDS line. What you are specifying here is the trade size of the hub (1/2, 3/4, or 1 inch) and whether the run dead-ends at the box or feeds through it.
5) Is the Crouse-Hinds EDS back box rated for outdoor installation?
NEMA 3R, so it is good outdoors against rain, sleet, and ice formation. That covers the usual tank farm, loading rack, and exterior process-unit mounting. NEMA 3R is not a washdown or hosedown rating, so for direct high-pressure spray or submersion you want a higher NEMA type.
6) How much space do I need to mount a single-gang FlexStation EDS back box?
Plan for a body measuring 5.9055 x 3.5 x 3.0625 inches, with the 3.5 inch figure also given as the depth. At 5.2 lb of Feraloy iron alloy it is heavy for its footprint, so mount to structure or a rigid strut, not to sheet panel alone, and allow bend radius clearance beyond the box for the rigid conduit entering the hub.
7) How many devices will a single-gang EDS back box hold?
One. The EDS back box is a single-gang enclosure, so it takes one device position, a single control station switch, pilot light, or pushbutton. If the panel schedule calls for a start/stop pair plus an indicator at one location, that is a multi-gang requirement and this box will not cover it.
8) Why is the EDS back box made of Feraloy iron alloy instead of aluminum?
Feraloy iron alloy is Crouse-Hinds' cast iron alloy, and it gives the wall strength needed to contain an internal ignition, which is the whole basis of a Class I, Division 1 explosion-proof enclosure, plus corrosion resistance for process environments. It is also why the box runs 5.2 lb in a single-gang size, which matters when you are hanging a string of them off unistrut.
9) Is this box approved for use in Canada as well as the US?
The FlexStation EDS back box is built to NEC/CEC standards, so it is specified against both the National Electrical Code and the Canadian Electrical Code for classified locations. That matters on cross-border process work where one drawing set has to satisfy both authorities.
