  1. If that is a header or beam in the photo it should have joist hangers attached.
  2. Back flow prevention.
  3. http://forums.mikeholt.com/showthread.php?t=173784 Are any of you folks considering getting off the arc fault bandwagon?
  4. 1" FMC is allowed up to 24 #12 or 33 #14. Derating is another subject.
  5. USE is NOT code compliant for interior wiring. 338.12(B)(1)
  6. Seems to me a responsible report would be "unknown", not just a guess.
  7. Indiana has exempted the use of AFCI's and TR recaps.
  8. As you know, ALL bathroom receps must be GFCI protected.
  9. Can not be within the foot print of the tub. The question is whether or not the deck in which the tub is mounted qualifies as part of the footprint. 2011 NEC 406.9©

    Sub panel ?

    I dunno exactly but there's a practice involving metal conduit between meter box and panel: If there are concentric rings left on either the meter box or panel enclosure after installing the conduit, a bonding wire must be run through the conduit from meter box to a grounding/locking bushing on the panel side I guess because the remaining concentric rings are easily damaged and are therefore not a reliable bonding connection. I disagree, although I always include an EGC within metallic raceways. Marc

Marc That's basically it, but it only applies to the connection at the service panel. As far as I know, you don't have to worry about it after that. ...so the knockouts, isolated so much by their nearly all around cuts, don't have enough area in common with the box to make a bond. BTW what happened to the red wire feeding the sub? I only see black ones coming in there, with one taped white. There is no red conductor for the feed. There ar two blacks, one behind the other. The other arguments throughout the thread about eccentric or concentric knockouts is moot for voltages under 250.
  12. I am curious. Exactly how would you install wyes, ells and tees?[?]
  13. Those are NOT 3 tab shingles.
  14. Personally I'd like to see a photo of the entire enclosure. If that is a service panel/disconnect the SER equipment grounding conductor should be terminated with the neutral.
