Many plans are submitted without the required separation of mains as per the 2020 Code. Especially when we get a 400 ampere meter main
combo with two (2) 200 ampere mains. This new requirement has been in effect for more than a year and still is overlooked when submitting a set of plans.
The old meter main combos that we used years ago are not Code compliant anymore per 230.71.
Till next time be safe work safe.
