| A problem with AC Power you may not have considered. Either way, I don’t see any AHJ issuing a permit for residential use of this equipment. Agree.If you read NEC Article 647 it clearly states 60/120V power systems are approved for use in commercial and industrial occupancies. Period..... NEC 647.3... | |
| A problem with AC Power you may not have considered. spatialking OP118 posts12-15-2018 1:31pm Do be aware if you spring for this - currently there are no NEMA receptacles or plugs designed for balanced 120VAC power. See NEC 647.7 (4) Exception: Receptacles and attachment plugs rated 125-volt, singl... | |
| To buy grounded or not to buy grounded. That is the question. jab431 posts12-14-2018 11:33amPS Audio made a power cord where you could unscrew the grounding pin. Yes. PS Audio states the grounding pin should only be removed for testing purposes only. Basically covering their butt. Audio-envy on the other ha... | |
| To buy grounded or not to buy grounded. That is the question. towertone24 posts12-12-2018 7:24pmLet’s establish a few electrical facts first;If a piece of equipment comes with a two-prong (hot and neutral) plug then the chases is bonded and passes any short to the neutral. The chassis is bonded to what? Not... | |

| Lowering House Grounding Impedance builder3119 posts12-08-2018 6:30pmJim, interesting, and I don’t know the answers. I wish I had a better understanding of the real world differences and interactions of the grounded (neutral) and grounding conductors. Thanks for the link, I’ll ch... | |
| Lowering House Grounding Impedance builder3116 posts12-07-2018 8:36pmWhat you described is the code requirement currently, as I understand it. The grounding connection is a safety requirement. Barring an electrical issue, it shouldn’t be doing anything at all. Again, that’s how I... | |
| Lowering House Grounding Impedance spatialking95 posts12-05-2018 11:19pmI have. I added a clean ground to my system, rather than use the house ground. I was amazed at how clean FM reception became. I had two FM tuners, one analog and the other digital but both improved significant... | |
| Going to have a dedicated line installed- What should i know to ask for? dumbeat OP71 posts11-27-2018 3:11pmIm in Brookly NY. Should have mentioned.

| Replacing/Upgrading AC Outlets The Hubbell 8300 has a different face material and its contacts are nickel plated; apparently the nickel plating will give the receptacle a slightly more forward presentation. Some will say that the nickel contributes a "brightness". The old stoc... |
