Electrical Service Entrance Upgrades are our specialty. It's the electrical installation that we have the most experience. Whether on homes or buildings, single phase or 3 phase, over head or underground, primary or secondary, 100 amp to 800 amp, we have done them. We will strive to minimize the disruption of your power and will provide generator power during the upgrade process if necessary. Our longest underground conduit pull is 500' with triple primary. Our longest direct bury primary is 1/4 mile. Contact us for a quote.
