Was at a local Junior High Scool last week. Three years ago I had professionally serviced/upgraded all their lights and added to them for a plotted rep.
plot package donation for
GymAtorium light plot. They had an actual
light plot design for general shows when I left the school staff for implantation of it.
Called last week from them... one
dimmer (shoe box dimmers) keeps blowing and doesn't work now. Want to go
LED and by the way replace the ancient
drapes.
My associate - the business quote guy (I'm the wiring/rigging guy) went to the school. We quickly saw the school staff didn't follow any install details or have a clue about what they were doing or even in purchased gear not installed.. even test what they did. We couldn't initially solve the problems, but me on the next day changed some circuiting in down scaling the design for what was actual fixed the theater lighting program.
So three years ago, I advised and they paid for replacement
tails to the electrics from the theater from 16ga SJT cables to the shoe box dimmers to 12ga SO. Such jumpers bought were never installed.
First
House Electric had eight duplex outlets semi professionally installed in the ceiling above it.... Assuming a minimum of 500w per
fixture... not a great idea given it was only four curcuits run back to the dimmers with 16 ga cable jumpers to the dimmers.
Bad me in assuming one duplex
outlet per
circuit for design in not testing that. Lots of
pigtail cords coming to the patch bay - most un-used -somewhere on
stage seemingly.
So in part of the design.. the maintenance person plugged in two lights per
circuit for the first four outlets causing over wattage problems when other next
outlet fixtures were plugged in. Dimmers are two
circuit 1.8K so 500w and 575w
fixture will cause trauma in loading. 2,075 watts on the
dimmer, once say another 1,000 watts plus on the assigned channels was added would be a problem.
School staff installing the lights never informed me of a problem by way of three years. They also didn't install all the onstage lights, and changed the placement of them in further destroying my balanced loading patch. This in addition to install of the
stage lights no longer allows the main drape to close.
Went well and beyond on initial install. Sold them cable and told specifically what and why, donated lights which in most cases were not installed by design..
Safety cables provided are where? Overall... school bought a bunch of wiring. The
fixture to source jumpers were used as with many of the fixtures.. Problems, self induced and or... a
quad box for outlets in the air, for a minimum of 500w fixtures, but 16ga
jumper to th
dimmer. And even when cable provided to fix it... Three years later, we have a problem and want to go
LED.
LED is out of their local school budget but we can give them a price to shoot for
. Out of flame proof
drapes is also out of budget but in measuring we can perhaps get that done. While there also install the lights and circuiting as per the
plot in how it was designed.
