Do you need something meggered? Roberts Electrical offers an insulation resistance testing service in Sudbury and the surrounding areas using a powered megohm tester. We can test the electrical resistance of most electrical equipment including motors, transformers and cables. Sometimes after a flood or fire an inspection authority will ask to have all of the affected wires tested to ensure that the insulation resistance is high enough to safely turn the power back on.
