Stephen D. Gazo Posted October 31, 2012 Report Share Posted October 31, 2012 I am guessing you didn't climb those steps for access? Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted November 1, 2012 Report Share Posted November 1, 2012 If the siding does need protection for current potential, shouldn't it be bonded to the GEC instead of having its own ground rod? Also, that looks like a hollow pipe rather than a listed grounding electrode. Quote Link to comment Share on other sites More sharing options...

Also, that looks like a hollow pipe rather than a listed grounding electrode. It is done for lighting. To take it to the ground I understand that lightning can be a source of electrical current in the siding. My point is, to equalize potential and reduce arching between the siding and other metal components in the house, the goal would be to "bond" the siding to the GEC (grounding electrode conductor). Many times this is done by connecting at the service equipment. It equalizes potential between the different metal components and reduces the likelihood of arching which could start fires. I don't believe that bonding aluminum siding is even required by NEC but if the goal is to reduce lightning hazards, it should be bonded to the GEC. It's ok for it to have its own grounding rod but it should not be independent of the other grounded systems. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted November 1, 2012 Report Share Posted November 1, 2012 What do you suppose the current rating is on an aluminum gutter rivet? I'd wager it's about as effective as tires on the roof of an aluminum clad mobile home. Someone needs a prozac. Quote Link to comment Share on other sites More sharing options...
Scottpat Posted November 1, 2012 Report Share Posted November 1, 2012 That it the type of attic that when you pull down the stairs you just kind of look at it for a moment. I really dislike pull down stairs especially when I see the weight limit stamped in big bold print and it says weight limit 200lbs, and I'm pushing 260lbs!

Jim Baird Posted November 1, 2012 Report Share Posted November 1, 2012 I have seen a full variety of broken/incomplete ones. Once on a new tract house doing a final for the AHJ, I told the site super he needed to cut the ladder to fit the floor. Just happened his "punch out" man was there with a battery powered skilsaw. He snatched up the folded leg and started to whack it off at random when I stopped him and said, "Let me show you, bro, how that is done". He had not a clue, but he did have a brand new truck outside. Quote Link to comment Share on other sites More sharing options...

Marc Posted November 1, 2012 Report Share Posted November 1, 2012 "Let me show you, bro, how that is done". Sounds like it involves MATH! Ugghh! No. I just put a 2X4 or 1X4 on the floor next to the leg I want to cut, mark it with a pencil then cut. Might have to do it several times. Learned it from my grandfather. What's your method Jim B?

Jim Katen Posted November 2, 2012 Report Share Posted November 2, 2012 What do you suppose the current rating is on an aluminum gutter rivet? I don't know, but I know from experience that it's well below 160 amps. I'd wager it's about as effective as tires on the roof of an aluminum clad mobile home. Someone needs a prozac. Any talk of bonding aluminum siding should begin with bonding *each piece* together. Quote Link to comment Share on other sites More sharing options...
