Re: X10 lamp modules

[adrian.lucas@xxxxxxx]

Are the fuses in the lamp modules "special" (high-speed?) or just
stand=
ard 2A plug top fuses?
If the former, wher do you buy them?

Let me guess.....
Is the lamp in question is mounted with cap DOWN ?

If so, it will almost always pop the fuse when it blows.
this is because, as the filament breaks it falls down and shorts out th=
e
support wires turning your 60W bulb into a 2Kw bulb or higher, hence th=
e
flash seen sometimes when a bulb blows.

DO NOT REPLACE THE FUSE WITH A HIGHER RATING OR SLOWER FUSE !!!!!

The fuse is there to PROTECT the triac in the dimmer
Fuses are EASY to replace, triacs are a pain.

You may remember the earlier threads mentioning "Ensure you have EASY
a=
ccess
to the module for fuse replacement".

When I was running my Disco several years ago, the high-speed ceramic f=
uses
for my lighting controllers were about 50p EACH. I could buy a triac fo=
r 30p
but a fuse can be changed in a matter of seconds, triacs took MUCH long=
er.

If you are unfortunate enough to blow a triac they almost always fail S=
HORT
CIRCUIT leaving the light permanently ON. If the fuse hasnt blown then =
you
still need to get to the module to remove the fuse to turn the light of=
f AND
you have the hassle of having to change the triac or buy a new module :=
-((

Oh....Almost forgot to say...

BUY SOME NEW BULBS....They will last a bit longer :-))

Whilst X10 modules are in season: I've put a lamp module to the
strenuous task of running a 60W lamp. Last week the bulb blew (in quite=

a big way) which took out the 2amp fuse in the module. I replaced the
bulb and the fuse (with one borrowed from a spare module) and all was
fine. The bulb has blown again this week, and blown the fuse again.

My question is - I can accept that twice is perhaps a coincidence (we
have a collection of second hand bulbs) but is it usual for module fuse=

to blow? Can you swap the fuse for a slower blowing type, or does it
blow so easily for a good reason? Just strikes me as a nuisance,
especially if the fuse is in an LD10 buried in the ceiling...
