Square D WS363 – Frequently Asked Questions

1) Will the Square D WS363 weathershield fit my transformer enclosure?
The WS363 weathershield kit is built for Square D transformer enclosure box numbers 17D, 17H, 18D and 18H only. If your transformer's enclosure box number is not one of those four, this kit will not line up with the mounting holes and you need the weathershield matched to your box number.
2) Can I add a weathershield to a Square D transformer that is already installed outdoors?
Yes, retrofit is the normal use. The WS363 kit uses a bolt-on mounting configuration, so it goes onto an existing 17D, 17H, 18D or 18H enclosure in the field without special tools. No need to pull the transformer.
3) What are the dimensions of the WS363 weathershield kit?
The kit measures 19.5 inches wide, 6.2 inches high and 3.125 inches deep. Use those numbers to check clearance above and around the enclosure, particularly the 3-1/8 inch depth if the transformer sits close to a wall or in a tight equipment room.
4) Is the Square D WS363 weathershield rated for outdoor use?
Indoor and outdoor both. The shield is gray painted steel, which is what gives it corrosion resistance in exposed locations, and its job is to keep weather out of the enclosure openings on the transformer box.
5) What is the exact part number to order for this Square D weathershield?
Order Square D WS363. That is the single model on this weathershield kit, built for the 17D, 17H, 18D and 18H transformer enclosure boxes. There are no finish or size options to specify, so the part number alone completes the order.
6) What standard is the Square D weathershield kit referenced to, and is it made in the USA?
The kit is referenced to IEEE 519-1992 for power quality performance alongside the associated transformer, and it is manufactured in the United States. For a government or institutional job with domestic sourcing requirements, that country of origin is on record.
