As defined by the NEC
Road Show Connection Panel (A Type of Patch Panel)
. A panel designed to allow for road
show connection of portable stage
switchboards to fixed lighting outlets by means of permanently installed supplementary circuits.
Sometimes known as an FOH Transfer Panel
. Running cables and cords from portable dimmers located backstage to FOH
Box Booms, Coves, and Balcony Rails through the proscenium
wall is problematic in many ways. Long runs are required; cords are unsightly; the prosc. wall is often a firewall that cannot be penetrated without proper fire stop. To alleviate this, many theatres have permanently installed circuits to locations DS of the proscenium. Often these circuits are also required to be used by the house
dimmers, thus the transfer panel part. Increasingly popular is the use of a road DMX input, so that the production does not need to carry dimmers for these locations; instead its console
controls some or all of the house dimmers.
A common misconception about such panels is that the circuits don't need overcurrent protection, as they can't be energized without being plugged into a dimmer
The supply devices of these supplementary circuits shall be protected by branch-circuit
overcurrent protective devices. Each supplementary circuit, within the road show connection panel and theater, shall be protected by branch-circuit overcurrent protective devices installed within the road show connection panel.
