INTRODUCTION

Meter panel upgrades typically cover changes from a 100 amp to a 200 amp panel. Meter panel replacement requires coordination with the utility company. Generally the utility will disconnect in the morning and re-connect the same afternoon provided the panel passes preliminary panel inspection. After inspection the city will release the meter to the utility company. You may call in an inspection request as soon as you have a scheduled date from the utility company.
