Today at the job someone came to me with a concern. It seems that one of the vinyl flooring guys were using a torch of some kind that drew about 14 amps at 120v one the same outlet another carpenter was using a halogen light that took 4 amps. The outlet is about 100 ft from the panel and the vinyl tool was on another 50ft (at least) extension cord. When the carpenter turned on his light you could see it pulsate. My initial thought was voltage drop. Putting my meter into the circuit I found it fluctuating between 112 and 118 volts. Is this a voltage drop situation, is this what is normally experienced with them??
