A friend of mine says that you must have a main breaker in a subpanel if it located more than 25 feet from the main panel. I have always used subpanels with main lugs and never had a problem. Is this something new in the codebook or is he wrong? I can't find anything in the 2002 codebook speaking of this.

Try this, when someone offers some code that just does not sound right, always just ask for a code reference. It's amazing what the response will be. Well not really.... :grin:

I asked him that and he didn't know. However he wasn't insisting that he was right he just thought that somewhere he had heard that or read it. Thanks.

I think it's time to tell him about "Charlie's Rule." I am hoping to buy a new camera, and I could use the royalties. :wink: :grin:

My standard reply now is "I don't believe you unless you show it to me in the book" or sometimes it's just "Show me the money!!"
 
Does the feeder to the subpanel have an OCPD on it's supply end? When your friend mentions 25' it sounds like he referencing the 25' tap rule.

Here it is,...


[quote=mikeholtnewsletter]

Tap 10 to 25 feet long
You can install feeder tap conductors up to 25 ft long without an OCPD on the tap, if they:
  • Have an ampacity that is at least one-third of the ampacity of the OCPD that protects the feeder.
  • Terminate in a single OCPD (breaker or set of fuses) rated no more than the tap conductor ampacity per 310.15 [Table 310.16].
  • Are protected from physical damage (enclosed in a manner approved by the AHJ, such as within a raceway). [/quote]
