I recently installed a 240 volt 7500 watt forced air electric heater in my garage. It seems to take longer to heat than I would expect, so I clamped it with my amprobe and it's pulling 13.5 amps on each leg. I would expect it to pull 31.25 amps at 240 volts. I called the manufacturer, but haven't been able to contact a living person yet. Am I missing something? My actual voltage is 248 v. Based on my measurements, it looks like it's only putting out 3240 watts. Any ideas?
