Aqua-lamp ALTR Transformer

[TurnerBFC]

Hi Guys,

New poster here.

Replaced the bulb and fixture on my Aqualamp standard 60W pool light. After 5 hours, it died. Took the cover off my control box and the wires to my transformer were frayed and actually broke one of them off just easily moving around the transformer.

Anyways, I don't need to buy the whole control box but just need the actual transformer itself.

Does anyone know where I could get a basic transformer that will step-down 120ac to 12ac for the 60W bulb?

Thanks!

I don't know but here is a bump to get this in front of more eyes.

Turner,

Check the transformer nameplate for the proper capacity. It is probably the next standard size up so it could be a 100 watt. Instead of wattage it will be stamped with VA (Volt Amperes) not watts. Volt Amperes are the same as Watts) You will find a number such as 120/12 Volt 100VA. Search for this number plus low voltage transformer and there are many electronics stores that sell them such as Mouser, Allied Electronics that sell them. Price should be less than $20. Be sure to photograph the wiring before you remove the transformer from the box and check the dimensions of the new transformer to be sure it will fit into your existing compartment inside the box. It must be installed inside the compartment to maintain code compliance. Code requires the segregation of low voltage wiring. If you're not sure what this means get a qualified electrician to do this for you. Wiring must be done right to avoid shock hazard in your pool and is worth paying an expert unless you are 100% certain you know what you're doing.

I hope this helps.

In addition to what Chris already said about the rating...

I'm assuming this light is underwater so make sure you get a pool rated transformer... don't buy a generic one because it could fail and electrify your pool (I am not an electrician)

The NEC (from 2014 I think) states:

680.23 Underwater Luminaires.

(A) General.
(2) Transformers. Transformers for underwater luminaires shall be an isolated winding type with a grounded metal barrier between the primary and secondary windings, and shall be listed for the purpose.

I believe this is so a coil failure (primary or secondary) will result in at worst a dead short to ground... you DO NOT WANT a transformer where the primary coil could short to the secondary
