I've mulled through the replies on my previous thread on how many lights is enough. This got me to thinking - how many lights per circuit?
I'm running D20 (2.4 KW) modules in a Sensor 3-48 rack. The distance from the Sensor rack to the catwalk raceway is fairly short - maybe about 30' to the start of the raceway (and another 30' or so to the end). That has 12 gauge wire - so I'm not worried about running two instruments per circuit if I use 575 W lamps. I'm comfortable running twofers in this situation.
The stage electrics are another issue. It is maybe 50' from the Sensor rack to the ceiling, another 40' to the terminal boxes, the length of the cable (35-40') down to the raceways and then the 40' length of the raceway. The wire is all 12 gauge. The total length is on the order of 130' to the start of the raceways.
I've got 750 W BTN lamps in the Fresnel instruments. At full power that's 1500 W on a 2400 W circuit. The circuit should carry the power required. Would it be advisable to run twofers on the stage electrics? My main concern is that the wire (and cable) from the trough on the wall to the stage electrics is maybe 30 years old. I did have it evaluated when the Sensor rack was wired in last year.
