Electricity & EquipmentQuestion 103 of 484
Plugging several high-wattage appliances (blow dryer, curling iron, steamer) into a single outlet through a power strip is dangerous because it can:
a.Overload the circuit, overheat the wiring, and start an electrical fire
b.Trip the GFCI even when no fault to ground exists
c.Reverse the polarity of galvanic machines elsewhere in the salon
d.Cause the equipment to operate on direct current
Explanation
Each circuit is rated for a maximum continuous load (often 15 or 20 amperes). Stacking high-draw appliances on one circuit through a power strip exceeds that rating, overheats the conductors, and is a common cause of electrical fires in salons.
