300.15 doesn't specifically mention a jbox is required when using sj cord.
So, switch to NM and use a box

Thanks guys, I might just place the transformer in a 4 or 5 inch box and make all my 110v connections in the box using sj cord with a plug.
anymore suggestions would be great.

I have given up on low voltage halogen lamps. If needed I opt for the GU10 mains type. I take them out when I can advise a custome to spend the cash. Have tried LED's also but light level output is not up to value yet.

I gave up on em as well. Half the time when the kids would slam a cabinet door shut with the light on, it would pop the filament. Should've given up on the kids instead.

I am very confused by all the responses. What kind of trany is it. If you have primary wires just sticking out of the trany then it must be in a box. Wac transformers have a special box you buy to house the trany.

any 12volt transformer with 120 or 110 on the primary side should be in a box

Yes, the primary side should be in a box. Are you looking to plug it in? Is this why you have SO cord? You can get 12V plug-in transformers. Personally, I prefer hardwired enclosed 120v lights whenever possible. 12V stuff can be very problematic.

mr-16s get too hot.. And they don't like vibration.
The transformers burn out too fast and are normally hard to get at though that small hole. (pot light)

Not to mention that when used in the bulb-down orientation as in a can light or on a track, the heat causes oxidation and failure of the terminals in the socket, everybody I know who has these lights eventually seems to have this same failure (cheap socket terminals?).
