Dude, seriously great video. Well explained and I appreciate the detail and breakdowns! Keep it up! More people are probably benefiting from these videos than you’d imagine.
Can you show/explain the drain. Ive been doing low voltage, but don't understand where to ground it- does it connect somewherein the panel. Thank again
@SJ-nl6xl Drain wires are used in cables in conjunction with a metallic shield to ensure effective grounding. The drain wire serves to complete an electrical circuit from the shield and carry unwanted electrical noise to ground away from the circuit. In other words, is so if the wire picks up static, the data traveling through the wire doesn't get interrupted or start acting up when you badge because of high voltage by the area you ran your wire or any other static sources in the pathway.
Yes, drain wires need to connect to Earth ground at the panel. You may be able to connect to the AC earth, but it's not always acceptable to use a common ground between AC and DC power sources. You can run a plain copper conductor out of your panel and connect to a ground rod or water pipe. In the panel, it's best to use a ground bus bar, but you can also just screw into an unpainted cabinet and ground that. Since it's just for signal quality and not for electrical safety, you have a bit of latitude in how you choose to handle it.
We usually have accounts with big wiring companies and get discounts because we buy so much cable, examples: EXCEL/ANIXTER/WIRECITY/ELLIOTT ELECTRIC, ETC.
