Service upgrade

Does anyone know of a good reference on upgrading electrical service? I'm going from 100A to 200A and plan to stage the new breaker box next to the current one and the new meter box next to the current one. The power company said they can jumper the new service then I can do all the switching later, but i'm not sure what they mean. I'm not sure what else to expect in an upgrade.

Thanks in advance.

I would do like you are doing and get new service inspected, the prepare for a change over. I am usually right there when the utility comes and ready, have some preliminary work and calulations done, breakers installed after inspection, connectors in box, any junction boxes needed to lengthen wires etc. As soon as the utility gets there shut the main off to the old one and begin moving the circuits to the new panel. By the time they get the new service ran you should have the critical circuits transfered such as fridge, freezer, heat and lights you need and you are good to go. I have also back fed the new from the old and moved some circuits over ahead of time,,,, make sure main to new service is OFF.

Connect a jumper between the existing panel and the new panel. This may require two 2-pole breakers, one in each panel. The 2-pole breaker in the new panel will be a "feed-in" breaker that energizes the new panel from the existing panel. With both panels energized you can transfer the existing cables from the old panel to the new panel with minimum disruption of your system. It best to complete the new wiring in the new panel such as the Grounding and Bonding connections and the Service Conductors from the meter prior to energizing the new panel. Don't forget to indentify as many circuits as possible when transferring the cables so you'll have an accurate record of circuit-indentification on the new panel.---Good Luck!!!!
