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,

Ernie- I'm reading in 408.16 that a panel such as you are describing is allowed two mains?? Also look at the Exception No. 2 for existing.

Yeppers- You sometimes see panels with split buss and a main for each set of buss bars. Pushmatic used to use them all the time. Thank God their no longer manufactured. The 200a. panel had two set's of buss and a 100a. main for each set.

iwire- Isn't that an Oldie? I think that one isn't legal any more Seems like we have about 5 mains. It's still a Lighting and Appliance branch circuit panel board. We have a guy in Metro Detroit that gets a premium for those old Zinsco breakers. Spmething like $50.00 bucks for the rare ones.
