Junction Box
Junction Box
Junction box for 12 V pool lighting — the most cost-effective way to feed several underwater lights from one safety transformer. The redesigned junction-box transformer cuts energy loss, and the sealed enclosure gives each lamp cable its own gland and terminal, so a lamp can be changed without disturbing the others. Mount it above the pool water level, at the distance from the pool edge that local electrical rules require, and keep the 12 V cable runs short and of adequate cross-section to avoid a visible drop in brightness on the farthest lamp.

Junction Boxes — frequently asked questions
What is the junction box for?
It is the waterproof enclosure where the 12 V cable from each underwater light meets the cable from the safety isolating transformer. Mounted above the waterline, it keeps every connection dry and lets a light be disconnected for service without touching the transformer.
Where is it mounted?
On the deck or wall near each light, above the maximum water level, with the light cable rising continuously from the niche to the box so there is no low point where water can collect. One box per light cable run is the usual practice.
Can mains cables be connected inside it?
No. The box is for the low-voltage 12 V side only. The 220 V supply stops at the safety isolating transformer in the plant room.
