Two pool related questions

Merry Christmas
1. The pool I’m wiring is within 5’ of the single family house with aluminum siding. I assume I would have to bond the siding with a #8. What would be the best way to do this, or what type of lug?

Do people still install Aluminum siding? I say replace it with something modern fiber cement lap siding aka 'hardy plank'.
 
Wood siding on the house but an aluminum down spout in the corner. The inspector required the electrician to bond the down spout at each break between fittings and the upright. It was ugly.
Not sure, but he may have had to bond the gutter. I believe there was also a window with aluminum cladding nearby that was a point of discussion.
Mike Holt has a story of some satellite installers that were getting shocked by the gutter on top of the house. Turns out the gutter was bonded to the bonding grid for the pool. In essence, the gutter was being energized from the grid where normally there would be no voltage up there. It's stupid to require something to be bonded that you would never come in contact with while using the pool.

As to the OP's aluminum siding, if an inspector insisted on it being bonded, I would see if the HO would put up a permanent barrier. Would be a lot better than seeing bare #8 and lugs run all over the place up the side of the house.

That is strange. I wonder what around the pool was getting energized.
I was actually thinking of the same thing and agree about a barrier or a cover to hide the #8's

In my case with the spa, it was set against the house foundation, in a corner and the down spout was very close to the spa. I found a pic before gunite. The down spout I think was re-located around the corner. The window was in question also.

That is what our bonding actually does. There is almost always voltage on the electrical grounding system as compared to earth away from any grounding electrode. Our bonding puts that voltage on all of the bonded parts of the pool to make everything the same voltage. However it is rare that the voltage on the electrical grounding system would be high enough to be able to feel. It it is that high, it is often an issue with the neutral, including the primary neutral for a single phase utility transformer connected line to neutral on the primary. I have see a bit over 30 volts from that condition and that can be enough to feel.
 
Gotta wonder how aluminum siding will respond to being splashed by chlorinated pool water.

IMHO there are enough stories of energized siding to justify bonding metal siding, but it is probably better all around to replace a well defined portion of siding with something non-conductive.

The outer surface of the aluminum siding is covered with a layer of vinyl now...I think that has been the case for a couple of decades, so it is really an insulated metal surface. Note I am only talking about the type of siding shown in post 6. Other types of metal siding may have continuity between the individual pieces of siding and may not have a vinyl covering.

A megger set at 1000 volts and held against the vinyl covering on the siding in post 6 showed infinity.

Throw in a salt water chlorine generator. Let's see how long aluminum lasts in that environment.
Many years ago, there pools with aluminum surface skimmers. They just crumbled over time. I saw them on both concrete and vinyl pools.
