Spike Tape is five field calculators for stage electricians. Numbers in, numbers out, easy to read in a dark theatre, and built to be checked against a hand-worked number rather than trusted on faith. LOAD — watts and amps per circuit, with the 80% continuous-load rule applied automatically. Balance a rig across three phases by circuit or by fixture, and see the neutral current floor for non-linear (dimmer, LED) loads.
