tied breaker handles for two different circuits

[kwired]

In 1998 this panel would be considered a lighting an appliance branch circuit panelboard and was required to be protected by not more than 2 overcurrent devices

It would have been considered a lighting and appliance panelboard if it contained less than 10 percent of installed breakers consisting of 30 amp or less and supplying line to neutral loads. Problem with that is if trying to use the six disconnect rule even one single pole installed in there is more than 10%. It had to have a main. The only way it could have been done is to have main lugs and up to six feeders, or branch circuits that do not supply line to neutral loads.

I have seen/heard of this in the past with lighting for baseball fields. They want to feed five lighting poles with five feeders from a main lug panel. Then whoever is management of the facility says since we have power here why not a 120 volt receptacle? OK, they install a sixth breaker (single pole) to power the receptacle but now have a lighting and appliance panelboard and it requires a main. Least costly solution was to install a two pole breaker, supply another panel - only needed to be 2 space panel then connect the receptacle circuit to that.

I don't have my old code book handy but does that requirement apply to service equipment?

just wanted to add that 225.33(B) does not apply to this installation. Having said that the applicable section, 230.71(B), says the same thing and Infinity has a great solution.

Yes, you're correct I did post the wrong section although the requirements are the same.

It should have applied to services only. If you have a panel fed by a feeder you will already have a main at the source of the feeder. It wouldn't comply with feeder tap rules because feeder taps have to terminate at a single overcurrent device.
