Intermatic PX300 – Frequently Asked Questions

1) Can I use the Intermatic PX300 transformer for pool underwater lights, or is it only for landscape lighting?
Both. The PX300 safety transformer is built for underwater lighting and landscape lighting, and it supplies 12-14 VAC on the secondary side. That is the range wet-niche and no-niche pool and spa fixtures run on, so one unit can carry the pool lights and the path lights around the deck as long as the total connected load stays inside 300 watts.
2) Does the Intermatic PX300 meet NEC 680.23 for a pool light?
NEC Code 680.23 compliance is stated for the PX300, which is the article covering underwater luminaires. That is the reason an inspector will pass a low voltage pool light fed from it rather than from a generic landscape transformer, which is not built to the isolation requirements of that article.
3) Why does the PX300 pool transformer have 12V, 13V and 14V taps instead of just 12V?
The extra taps compensate for voltage drop on the run. The PX300 puts out 12V, 13V and 14V, so on a long wire run to a far fixture you move up to the 13V or 14V tap and land near 12V at the lamp. Short runs stay on 12V. Feeding a 12V lamp off the 14V tap on a short run over-drives it and shortens lamp life, so pick the tap after you measure at the fixture, not before.
4) What input voltage does the Intermatic PX300 need, and can I run it on 240V?
120V input only. The PX300 takes a 120V primary and steps it down to 12/13/14V. There is no dual-voltage primary on it, so a 240V feed is not an option; if the equipment pad only has 240V available you need a different transformer or a 120V circuit run to the pad.
5) Can the Intermatic PX300 transformer be mounted outdoors at the pool equipment pad?
Yes, it is built for it. The enclosure is steel with a weather-resistant finish, and the unit is intended for outdoor pool and spa environments. Mount it upright on the pad wall or post per normal practice for equipment-pad gear, keeping it clear of splash and direct discharge from the filter.
6) How do I mount the PX300 and what size wall space do I need?
Top and bottom mounting brackets come on the unit, so it hangs flat against a wall or post without a separate mounting kit. The enclosure measures 7.25 inches high, 5.25 inches wide and 4.5 inches deep, and it weighs 11 pounds, so put the fasteners into a stud, block or a post rather than into siding alone.
7) Does the Intermatic PX300 need a separate breaker or fuse on the low voltage side?
Circuit protection is built into the PX300. It disconnects automatically on an overload condition, so an added fuse block on the secondary is not required to protect the transformer itself. The 120V primary still has to be fed from its own properly sized branch circuit with the GFCI protection the pool installation requires.
8) What is the exact model number to order the Intermatic 300W pool and spa safety transformer?
Order Intermatic PX300. That is the 300 watt unit with the 120V primary and 12/13/14V secondary in the beige steel enclosure. Intermatic's PX series runs several wattages, so confirming the 300 on the end is what separates this from the smaller units in the same family.
9) What color is the Intermatic PX300 enclosure?
The steel enclosure is a beige/ivory finish, which is what Intermatic uses across its pool and spa equipment-pad line. If you are standardizing a property where the timers and sub-panels on the pad are already Intermatic beige, the PX300 matches them rather than standing out.
