ZoneLoad

ZoneLoad is a seat power board for a hall, cafe, or workshop. Pick a zone, place seats as a rig times a count, and read three results on one screen before you open: circuit headroom, cooling, and overnight electricity cost. A zone stores voltage, breaker rating, cooling capacity, price per kWh, and a note. A rig stores watts per seat. Change the count or the watts and every result updates together. Circuit. Current is total watts divided by voltage. Usable capacity is the breaker rating times 80%. The board shows the current, the headroom, and how many more seats fit at the current average watts. Over 80%, it shows the excess amps and watts and does not suggest adding more seats. Cooling. Seat power is counted as heat, one watt of electricity to one watt of heat, and compared with the zone’s cooling capacity. A shortfall stays a shortfall. Night. Overnight cost is kilowatts times the…
