  1. That's interesting. Refrigerators have thermostats that switch the compressor on and off, and relays at the compressor terminal box that switch the start capacitor in and out of circuit. Switches generate arcs. Maybe the AFCI circuitry is designed to ignore these refrigerator arcs but this arcing can change as these parts age. I can see AFCI's tripping when the appliance becomes older yet still works and ruining a great deal of food.
  2. That's why I didn't recommend a double underlayment on this 2.2/12 roof. The problems won't stop in this couillon contractor environment. I went with the modified bitumen recommendation, hot mopped and in the client's choice of color.
  3. Looks like they've started a roof covering replacement. Tell them they should finish it. MJR....Erby's the sort that can fly like that. I seen him before, perched atop a tall chimney, about to disappear in the clouds. Got some pretty amazing fellas here. Had one that could jump over tall buildings.
  4. Thanks guys. That's what it'll be.
  5. Yesterday's house had a roof pitch of barely over 2/12 with 3-tabs on top and leak issues throughout. I'm trying to think of a more appropriate roof cover, something not ugly for this residential area. We're a hurricane prone area so metal panel is out because wind-driven rain will find it's way under the ridge cap and breach the roof cover. Any suggestions?
  6. Doesn't make any sense. That tie in doesn't let you drain both tanks. You still need to open each bib at the bottom to do that. I doubt the manufacturer intended these two tanks to be installed in series. That HWH design doesn't lend well to a series connection. Expect hot water pressure regulation issues.
  7. Kurt's more like 62, 'bout the same as I. I'm feeling it for sure but I'm still a long way from slowing down on inspections. It keeps me young I think. I'll have to be forced into retirement, won't voluntarily quit for as long as I still need to eat.
  8. One of my more commonly used boilerplates: If your electrician says you don't need it because the house is old, fire him and find someone else. Electricity doesn't know how old the house is and doesn't care. It'll shock folks and start fires just as easily on an old house as it will on a new one. If the wireway is metallic, then that green neutral should be replaced with a white one. If it's not metallic, that dryer needs four wire service.
  9. It could be they're using that bus for a ground bus and that's ok. The two branch circuit neutrals nearby actually end up on the factory neutral bus. The foil barrier should be removed. It doesn't make sense to put an ungrounded sheet conductor that close to an SE. I can't think of a cite...not that one is needed. I'm sure there's more. That enclosure isn't rated NEMA 3. The plywood door doesn't make it ok.
  10. Is this it? It's Viega. It's a compression fit and needs a special tool (page 5).
  11. The 2000 IRC does say 'equivalent' when applied to the ceiling but it doesn't say that FRT is an equivalent. Your word should stand until the agent has docs saying otherwise and proof that the stuff installed is actually FRT plywood. Hearsay doesn't get much regard from me.
  12. That article really drives the point home. I like the view that inspecting the house is half the job. Writing the report is the other half. Did I get the grammar right?
  13. One flight of stairs led to another, and another, and another until finally the light behind dimmed and a faint red glow appeared up ahead.
  14. Ok. I was assuming that bonding to the neutral took place only within the three main panels which is where the upstream end of the EGCs are, not within the service disconnect. That's how I've done it. Bonding at multiple locations situated upstream or downstream of each other is what invites neutral currents into the EGC's but these three main panels are not either upstream or downstream of each other.
  15. Why would there be currents through and between the enclosures when the EGC's and enclosures of each main panel are bonded within the respective panel?
