My tenants in the shop have called me out for the third time
because the
lighting fuse blew when they turned on their miniature halogen
chandelier
and one of the lamps blew at switch-on. To me, continuously blowing
fuses
means a faulty appliance, and in this case I definitely blame the
halogen
chandelier. I hate the things. I should never have installed it for
them,
but they'd already bought it and "it looks sooooo nice!!!".

Put a dimmer on the chandelier as they usually have soft start so
less
chance the lamps will blow and take out the fuse.


The lamps will take out the dimmer instead ....


Not this one, it is fine for halogens at its advertised rating (I have
200w of GU10 on one without any issues at all).

No dimmer is flashover-proof.

Not sure why that is relevant to this part of the thread, if the OP
puts that dimmer on, which has soft start, and leaves the 5A fuse in
place, I expect it will be enough to prevent the fuse from blowing.


What he means is that WHEN you get a flashover WHEN one
of the bulbs dies, the dimmer will have to be replaced.


The dimmer on my gu10s lasted 22 years. When I took it apart a capacitor
had burnt.
As this wasn't in series with the load some fault other than a lamp
caused it.
