Hello,

I have a couple of X10 controlled appliance modules (see link below) which
are essentially a remote controllable relay. I wish to use some of these to
remotely switch floodlights on and off. However, they only have short
lengths of single insulated wires coming from them. See he

If I wire this into a junction box, this will leave exposed single insulated
wiring. My understanding is that all accessable wiring should be
double-insulated - is this correct?
Do I need to mount these modules inside an enclosure to make them
double-insulated?? (And "safe"?)

Many thanks,

Alan.

Incidently, it's usually often to buy the plug-in appliance modules.
If you disassemble them, you will find they consist of the part you
bought, with the addition of a 13A plug/socket/fuse. ;-)

Yes as Lurch said. You could mount them in the top of a box with
the upper part exposed for setting the housecode and unit numbers,
but with the bottom opening and wires inside the box. That wouldn't
be suitable for outdoor use though.

You can also get DIN rail mounting ones which fit in a consumer
unit. Actually, I bought an empty consumer unit just for mounting
these. You could fit them in a waterproof CU or DIN rail box for
outside use. The DIN rail ones are more expensive than the plug-in
appliance modules though. The DIN rail lamp module is much better
quality unit than it's plug-in equivalent though, always doing
switch on/off through a smoothed dimming operation, and it includes
a connection for operation via a momentary action switch if
required, quite separately from X10 operation. (Also claims to
support 'professional X10' whatever than is -- I think it might be
scene settings, but I don't have anything which can talk 'professional
X10' protocol to it.)

Take your pick, sigh...

Andrew,

I found some 'X10 professional' bits he
http://www.homeautomation.eu.com/category/6

I like the look of the 4 channel dimming transmitter to fit inside existing
light switches!

I need to use the wired appliance modules to control some (fixed)
floodlights, so plug-in modules won't help.
I havn't used the DIN units yet, but may try them soon. However, looking at
the one on the letsautomate website, if I fitted it into my existing CU it
would't provide any current limiting breaker functionality like a MCB so
would need fitting into it's own box downstram from the CU. They don't
mention that on their website so I bet some people have them in CU's
unprotected!

Well whaddya know, I'm a pro and didn't know it! Didn't realise that's
what it was. I've just been speccing some of that up for a job,
thought it was just normal X10 stuff but a different make.

That's who I bought most of my X10 bits from. They were the
cheapest supplier I could find at the time, with a good
range of items.

floodlights, so plug-in modules won't help.

The point is, if you take a plug-in module apart, you end up
with exactly the item in your photograph -- that's just the top
half of the plug-in module. Plug-in modules are often cheaper
(although not from that supplier).

I havn't used the DIN units yet, but may try them soon. However, looking at

Correct.

would need fitting into it's own box downstram from the CU. They don't

or you cut the buzz bar short and just use the rest of the CU
case for DIN rail mounted things. I used a separate CU case
as a distribution/switching box for lighting. I also included
a 3A Type B MCB to protect each DIN rail X10 dimmer, in the
hope it might protect the triac if a failed lamp arcs across.
They have a 20mm fuse on the front, but MCB's are probably
faster operating and the dimmers are expensive enough that I
would like to protect them best I can.

Pulled a plug-in module apart and confirmed this. "wired" version comes with
a mounting bracket which could be useful though.

Didn't know this - do now, thanks.
