So I've started adding movers to my LX, and have the issue of getting non-dim AC to them. My current way of doing so is with an extension cable in a regular outlet at stage level, tie-wrapped to a conduit that runs up to batten level, tie-wrapped to the slack portion of the dimmer power feed (I have motorized winches for my LX), and then left loose at the end of the batten near the dimmers. I then run another extension from batten-end to fixture when necessary.
To date, I have only used the movers for small perfomances where not many other fixtures were used and the total show ran less than an hour.
I am worried that running a standard extension cord near my fresnels at full power for 2 hours would be hazardous. Are my worries valid? If so, what is the appropraite cable to use?
