RE: G9 capsule takes out C-BUS Wireless Switch Doh!

["Andrew Walker \(CV/ETL\)" <andrew.walker@xxxxxxxxxxxx>]

Yeah, hes already sent it back to c-bus shop and they are going to
replace it no problem.  The tech guy there said it is always happening
and depends exactly how the bulb goes, normally a short-circuit with a
bright flash.

I would look for internally fused lamps first - many of the branded
lamps from the likes of Osram etc are internally fused to limit the
current drawn when the filament blows to try and prevent this kind of
damage to sensitive equipment. Don't know if the switch can be easily
repaired, I know that some Futronix users have returned their damaged
dimmers to the manufacturer for new triacs to be fitted when they
experienced these problems.

I recommend two C-BUS Wireless switches to my brother for
Hall/Stairs/Landing use.

Each switch has two 200W channel capacity. One channel has 3 x 40W G9
capsules on it and the other channel 1 x 40W bulb.

Everything has worked fine for a few months until one of the G9's blew
and took out the main fuse box 6A lighting circuit but seems to have
also BLOWN the Wireless unit with neither channel working.

I then thought maybe he sould have had a type-B MCB on each channel
output of each switch. This is easy to do on my 8 channel dimmer unit in
a DIN enclosure but on a switch designed for retro-fit use replacing an
existing light switch its a bit tricky.

Just wondered if anyone had an opinion on this, should he be protecting
each output with an in-line fuse, maybe in the back box if he can fit it
in? I suggested he needed something like what you get on the back of car
stereos, maybe a 1 Amp quick blow fuse?

Any ideas what I can suggest he dose?
