>>  Hi Geoff!
>>
>>  Please see 2002 NEC Art. 312.8 " Enclosures for Switches or Overcurrent
>>  Devices".
>>  The first sentence says it all " Enclosures for switches or overcurrent
>>  devices SHALL NOT be used as junction boxes".
>>
>>  During my 30+ years as a journeyman, I have seen breaker panels with wire
>>  nuts and taped split bolt splices, it is not goog practice or acceptable.
>>
>>  We all should know the NEC requirements as well as we do the solar.
>>
>>  Hope this helps.
