Some clarification also if possible. By way of five
dimmer packs, do you mean five individual dimmers
in one pack or a rack of five say of eight way
dimmer packs all having the same problem?
On each
dimmer is also five lighting fixtures or given it's normally eight dimmers per pack how are these 25 lights distributed including their wattage?
Ditto on the model of the
dimmer pack and wattage of the fixtures.
Also how many phases are feeding the pack / what type of
power service is feeding it such as three
phase wye (120/208v), single
phase three
wire (120/240v), or single
phase (120v). Might it be blowing fuses powered by one specfic
phase of
power or all?
What's the
voltage coming from the service panel than as a second reading at the
dimmer pack? Also verify both
voltage readings on all phases not just in reading the
neutral to hot but also hot to
ground.
As a general question and always, when is the last time this/these
dimmer(s) had a service
call?
"fuses blow almost daily on one of them. each time its a different pack".
Again with telling what loading is on what
circuit/
dimmer, at what
point are they blowing, when turned on or at some
point say when that
dimmer is at full. This at full during a show's run but not all the time? What type of lighting control do you have also if fuses are blowing at random on dimmers - two scene pre-set where say an overloaded
dimmer might not be at full every night or computer scene based where it's the same
dimmer level every night? More than one
fuse per just about every night at a time or only one, and frequently one of a few select dimmers but not per say all the dimmers/
dimmer packs out of five?
