Title: Hot Wiring
Post by: lfdunn1 on May 04, 2011, 06:24:03 PM

Will hot wiring an X-10 component (e.g., a WS12A dimmer switch) (i.e., connect it without turning off line power at the breaker) damage the component?

You could damage an X10 device by hot wiring it. Not that it would guarantee a blown module.
Biggest problem could be the person wiring it ending up dead or harmed.
Why do you even want to wire one with the power on?

Why hot wire?  Only because I don't want to walk to the breaker panel in the garage "every time."  By "every time," I refer to a current trouble-shooting matter in which an old, mechanically failed WS12A-type switch was replaced with a new WS12A that worked for two days; then quit.  I have another new WS12A and will wire it with the power off...as I usually do. 

BTW, the label on the X-10 WS12A module says to wire Line-to-Black and Load-to-Blue but the instruction sheet in the package says just the opposite.  X-10 customer support said to follow the directions on the module; not on the instruction sheet.

Well just to say so, if you hook the hot wire up last how does the device no weather  or not you just turned it on.

Just  a thought.  Please turn it off !!! :o

I have not see anything definitive on the line and load colors to use.
Guess you use what X10s Customer Service said. They should know.

FWIW,  I've always wired them line-to-black  load/blue.

I'm pretty sure that wiring them the other way causes the impedance to change in such a way that the lamps may turn on, but not off.

The schematics of the WS467 {WS12A has a nice paddle over the button}. Shows Line as Black and Load as Blue.

No it won't. I know a guy that worked in the industry and he never shut off the breaker, he always just made sure he wasn't grounded. Even if he touched a hot wire nothing would happen. Unless he accidentally touched the ground wire. Or the box.

Well Deemar, Some day he maybe injured.

It only takes ONE mistake to kill you and for the typical end user it is extra dangerous.
