Purchase a non-contact infrared thermometer. ???It???s like a laser gun that one can point at electrical busways, control panels, switch gears, motors, etc. and it tells you if there are hot spots,??? says McCutcheon. ???These hot spots could mean you have phase issues or other problems with your electricity which can lead to overheating and costly repairs.
