Re: EIB versus CBUS

["shieldsauk" <ha@xxxxxxxxxxxx>]

Interestingly I've only lost one LD10/11 (admittedly out of only 6
installed) in 7 years. And
that was when a builder put a chisel through a cable.

I do find that the circuit breaker feeding that group of LD11's trips out
whenever a bulb
goes.

Being used to LD11's I was slightly surprised to find that CBUS advised
protection on each
load but I can understand it, I'd hate to lose four hundred quid's worth of
dimmer every
time a bulb blew.
