Square D 7400WMB18M19M20M – Frequently Asked Questions

1) Which Square D EX-Series transformer enclosures does the 7400WMB18M19M20M wall-mount bracket fit?
The Square D wall-mount bracket, model 7400WMB18M19M20M, is sized for EX-Series low voltage distribution transformer enclosure box numbers 18M, 19M and 20M. If your EX transformer carries a different box number, this bracket is not the right kit for it, so check the box number stamped on the enclosure nameplate before ordering.
2) Can I wall-mount an EX-Series transformer instead of setting it on the floor?
That is exactly what this bracket is for. It converts an 18M, 19M or 20M EX-Series transformer enclosure to a wall-mounted installation, which keeps the unit off the floor in tight electrical rooms and mechanical spaces. The bracket is the mounting accessory only, not the transformer.
3) Is the Square D EX-Series wall-mount bracket acceptable for a seismic installation?
The bracket has been shake table tested to ICS ES AC 156. For a project with seismic anchorage requirements, that is the test reference to put in your submittal package. Anchorage into the wall structure itself is still the installer's responsibility and is governed by the building's structural drawings.
4) Does this bracket work with DOE 2016 compliant EX transformers?
Yes. The bracket supports DOE 2016 fully compliant EX Transformers, including the units with separated primary and secondary terminals used in harmonic applications. New-construction and replacement transformers sold today fall under that efficiency standard, so the bracket suits current EX stock in the 18M/19M/20M box sizes.
5) Do I get the transformer with the 7400WMB18M19M20M, or just the bracket?
Just the bracket. The 7400WMB18M19M20M is a mounting accessory for EX-Series transformer enclosures and is ordered separately from the transformer itself. Order it alongside the matching 18M, 19M or 20M EX unit if the install is going on a wall.
6) What is the Square D 7400WMB transformer bracket made of, and will it match the transformer enclosure?
Gray steel. It matches the standard gray finish on Square D EX-Series transformer enclosures, so a wall-mounted unit in a visible electrical room or back-of-house space looks like a single assembly rather than a mixed-finish retrofit.
7) Is the Square D EX-Series wall-mount bracket made in the USA, and is it RoHS compliant?
Manufactured in the United States by Schneider Electric under the Square D brand. It is ROHS Eur compliant, mercury free and free of toxic heavy metals, which covers the usual procurement checkboxes for government, healthcare and education specs.
