LQB said:Yes, whatever is distributed to the breakers needs a filter so if the panel box bus is 3-way to the breakers/circuits, then you will need 3 filters – preferably close to the box. It also means that you’ll need 3 more breakers.
LQB said:If the cable is shielded then its as good as BX. If the outer layer is not metalized, then it is not shielded.
No, it's not shielded. I've never seen or heard of such a thing here, even in my French "Big Book of Electricity".
LQB said:Grounding is one of the commonly overlooked areas – even by the power folks. Neutral and grounds should be bonded ONLY at the service entrance panel – nowhere else. You want all current headed to ground to actually get there (the voltage drop has already occurred across the load). The resistance looking back towards the transformer that feeds the house may not be all that low. So you want a very low resistance path to ground – the ground rod. If this resistance grows (with time, age, etc), then current will return through the ground/neutrals setting up ground loops around the house. One theory is that this may exacerbate the solar inverter noise as well (I have no explanation for that if true).
Here they do stuff a bit differently. You never bond neutral-ground at the panel. The neutral at the local transformer is grounded, and it's strictly verboten to bond neutral to the local panel ground in an installation. They also are rather emphatic about not bonding ground to water pipes and that kind of thing.
Well, we can dream...
