Had an automatic pool cover installed when renovating pool. Pool cover was installed by a factory approved installer for my area. I watched as the installer connected braided bond wires which are sewn along each long edge of the cover by screwing them to the axle the cover winds onto. I believe the braided wires connect to a metal bar which I'm guessing is embedded in the front edge of the cover.
Afterwards, an electrician came to do finish wiring, and connected a bond wire of my bonding system to a couple of points on the framework of the cover mechanism.
After he left, I poked around with an ohmmeter and found there was no bonding to the aluminum track that runs along both sides of the pool. I bonded those no problem but then I came across a really perplexing bonding issue.
The main metal axle of the cover assembly showed no continuity to the framework. It's supported by plastic bearings on both ends ends and the motor connects to it with a plastic friction clutch. So from what I can tell, there's no way to bond the axle. It's definitely metal, about 15' long and within 5' of the pool edge which means it should be bonded. I can't be the first person to notice this so is it generally ignored, or since the equipment is UL listed, does that negate the need to bond mechanism specific components?
Seems like there should be a rotating metal contact to bond the axle. I imagine that would be quite expensive so is it ultimately up to the end user to come up with a fix?
Any comments are appreciated.
