    Best Grounding Practices

    the techniques/methods to do so are somewhat well documented. see NFPA-780 as a reference. See Annex-C
    i like isolation method. PVC can give ~55kV/mm dielectric ability. sched80 PVC can provide about 267kV dielectric. thus, having a big down connector that has very little ohms is key.

    I moved this to it's own thread since it is more about lightning protection than it is about pools.
