I was reading an Old IAEI news (November 1998). Page 20. Which stated this section applies to trailer , and Home services. One main if meets this classification. I could find nowhere since then this has been revised.Anyone have any Comments on this ?? Another words Trailer and Home services or any service matter of fact with 10% or more of its breakers 30amps or less with a neutral connected load WOULD be required to have a Single main Breaker,
