An electrician several years ago moved our main panel from outside to in. He used a 3 wire SEC from the meter base to the panel (which serves as the main disconnect). It runs about 15 ft under the house in the crawl space and then up the interior wall to the panel. Now I want to have a main disconnect placed under the meter base (with a few breakers to eventually feed a workshop) thus making the main panel a sub panel, and I am inquiring to if we can simply add a 4th wire to the SEC cable (I am envisioning taping it to the existing cable jacket) or do we need to strip out the whole 3 wire set and replace with a 4 wire SEC.
