re-use underfloor heating?

So I put this high hat LED in SUPER BRIGHT. Now normally I would just get a dimmer switch. But the switch I have is actually has a built-in timer. now I was wondering since I have access to that wire up in my attic they made A dimmer switch that I can wire and inline and and adjust it to my liking and never have to touch it again. I also had another thought about putting a junction box and a dimmer switch in my attic but I do not have enough room to do that anyone have a solution? Thanks

I have seen posts on this, but mine is slightly different. My washer is 4 years old (front loading LG washer). It has been working fine until recent weeks it has been tripping circuit breaker in the breaker box, but [u]not[/u] while it is running, it is always after some loads of wash...come back to do another load the next day..it doesn't power on. Go down to fuse box and it has been tripped for some reason. From what I can tell it is a dedicated breaker for the washing machine, it is rated to 30 amps (breaker switch), which I really only need that to be rated to 20 normally, but that is what it is hooked up to at this point. The outlet for washer is a [u]Non[/u] GFCI outlet and always has been. The outlet is also first powered by a power switch (like a light switch), so the switch always has to be turned to the on position in order for the washer outlet to get power and then hence the washer gets power. So what I did first is change out the washer outlet with a new 20 amp outlet...plugged it in....worked fine for several loads, and then came in to laundry room after 2 days to do another load....washing machine has no power again...circuit breaker has been tripped somehow again mysteriously. So something is causing it to trip without it even running. Any thoughts on what is going on? and what is next step? I might replace the circuit breaker in the breaker box and see if that helps next.
