---------------------------------

Normally a permit is needed for any major electrical upgrade. The permit cost is very different statewide. If needed, the upgrading process might include new service pole, new service feeders and adding copper grounding rods.

---------------------------------

COST FACTORS

Position - Inside the wall (flush-mount) or On the wall (surface-mount)
Circuits - How many pre-existing circuits in the panel
Grounding - Additional grounding might needed
Feeder - Size and Length of the panel feeder

When you upgrade the electrical panel to 200 Amps to meet these new demands, you can install new devices and appliances without any problem of running out of juice or breaking their electrical system.
