B-LINE ES-727220-4 – Frequently Asked Questions
1) Can the Eaton B-Line ES-727220-4 enclosure be used outdoors where it gets hosed down or rained on?
Yes. The ES4 enclosure carries a NEMA 4 rating, so it is built for indoor or outdoor use against windblown dust, rain, splashing water and hose-directed water. The seal comes from a closed cell neoprene gasket on the hinged double doors, and the carbon steel body is painted ANSI 61 grey. It is not a NEMA 4X, so it is not stainless or corrosion-rated for washdown chemical environments.
2) What are the actual outside dimensions of the ES-727220-4 ground mount enclosure?
72 inches high, 72 inches wide and 20 inches deep. That is a two-door cabinet footprint, so allow for door swing clearance in front of the full 72 inch width before you set the pad location.
3) Does this Eaton B-Line ES4 enclosure come with a back panel or mounting rails for gear?
No. It ships with no mounting provisions inside, so the sub-panel, mounting rails, or panel brackets you need to hang your gear are a separate line item. Plan the interior mounting kit into the order or you will have an empty steel box on site.
4) How do the doors latch and can they be padlocked?
The double doors use a 3-point latching handle, and the handle has a key lock padlock provision so you can secure it with your own padlock or key cylinder. Three-point latching pulls the door tight at the top, middle and bottom, which is what keeps the neoprene gasket compressed evenly for the NEMA 4 seal.
5) Is this enclosure acceptable for a UL listed industrial control panel build?
The ES4 enclosure is certified to UL 508A, the standard for industrial control panels, so it is the right shell for a control panel that has to be built and labeled to that standard.
6) Can the ES-727220-4 be wall mounted instead of set on the floor?
No. It is a ground mount enclosure, meant to sit on a pad or floor and be anchored at the base. At 72 by 72 inches and 613.3 lb it is not a wall-hung box. If you need it on a wall, specify a wall mount NEMA 4 enclosure instead.
7) How much does the ES-727220-4 weigh, and can two people set it?
613.3 lb empty. That is a rigging job, not a two-man lift. Have a forklift, hoist or crew and a prepared, level pad ready before delivery, and remember this is the bare enclosure weight before any gear goes in it.
8) Are there knockouts in this enclosure for conduit entry?
The ES4 is supplied without mounting provisions inside, and conduit entries are field-made. On a NEMA 4 cabinet every penetration you cut has to be closed with a rated watertight hub or fitting, otherwise you lose the rating the gasket and 3-point latch are there to provide.
9) Will this enclosure match the other gear in my plant for color?
It is finished in ANSI 61 grey, the standard light grey used across most industrial control gear and switchgear, so it will line up with existing panels in a typical plant lineup. Country of origin is the US.
