that is very odd ball item and i never heard 150 amp meter socket at all i did check my catlog book to see the listing there were none listed for that size and most common size are 100 , 200 and class 320 socket ( basically a 400 amp socket 320 amps useable for home useage ) and commercal 600 class (bolted type ) for bigger one we use ct's but never 150 at all for 150 amp service i use the 200 socket and use 150 main breaker that how we classifed it .. the cost between 150 and 200 main breaker box is not much diffrence anyway
merci marc
