Sealing Hub for Hazardous Locations

The Appleton Century Crofts ES10075 is a malleable iron conduit fitting rated for Class I, Division 1 and 2, Groups A, B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III environments. It provides a vertical sealing point for conduit runs in hazardous areas.

Vertical Orientation and Fill Limit

Questions about this item

How does the 25 percent fill rating affect the number of conductors I can install?

The 25 percent fill rating limits the total cross-sectional area of conductors inside the hub to one quarter of the internal volume, so you must calculate each wire's area and keep the sum within that limit.

What does the Class I Division 1 rating mean for daily operation in a hazardous area?

It certifies the hub for locations where flammable gases or vapours are present continuously or frequently under normal conditions, providing a flame path that contains any internal ignition.

How do the UL 886 and CSA C22.2 No 30 standards govern the hub's construction?

UL 886 and CSA C22.2 No 30 set the design, material and testing requirements for sealing fittings, ensuring the malleable iron body and threaded joints maintain integrity in classified locations.
