OK so we had 3 electricians bid on bringing electric out to the pool and to do bonding. 2 have experience with Jacuzzis and not pools but understand the concept of bonding. The one with 4 above ground pools and 5 in ground pools said he would drive 8 ft rods into the ground and that the copper halo is not needed--- so he is out of the running even though he did pools in Utah and Nevada. 1 is an electrical engineer as well as an electrician. Bonding is cheaper than being electrocuted so we are not going the cheap route
#1 does only the vertical support in 4 places around the pool need to attach to the copper halo ( 18 ' x 48" metal sided pool, top rail metal, vertical support metal )? One electrician thought the top rail should be bonded to the metal coping that sits over the plastic coping and all tied into the copper halo in the ground. His rational is if the metal coping can be touched it needs to be linked into the bonding. It's easy to touch inside the pool.
here is a photo of the top plate with plastic cover removed

at the top of the photo is the metal coping. It could be galvanized if that matters. Though it is over the vinyl liner it is a bit wavy and makes contact with the underside of the toprail. I can fit a finger between the top rail and this metal coping so there is room for some gizmo to connect.
#2 can one vertical support be removed to drill a hole for the direct burial lug to be bolted on? I read some people fish a bolt down from the top-that's got to be hard to tighten. Then we would remove the others 3 one at a time and connect the direct burial lug.

We hope to build a small deck 8 x 10 ' where the plastic ladder/steps are. I decided against metal balusters and go wood.
