| Ground voltage!! This thread is excellent at demonstrting how clueless this forum is about electricity. It will be hard for the OP to figure out what to do based on the various answers here. It appears you have properly measured 80 volts ground to neutral. ... | |
| Ground voltage!! bushikai OP 10 posts 11-04-2022 at 04:03pm Hello, Sorry for the confusion is 80 volts earth and neutral. @bushikai Just a guess your multimeter was set on auto scale and you read 80 mV (millivolts). Not 80 volts. Look to... | |
| Isolated ground in dedicated room/new construction? Would it present as sounding grainy /static? I figured the recordings that have some grain were from the recording. @ronboco Possibly. For a test, turn off the circuit that feeds the dimmers and LED lights at the electrical panel. The... | |
| Isolated ground in dedicated room/new construction? @ronboco Yes, and that includes the branch circuit wiring from the load side of the switch to light fixture(s). When can lights are used in a ceiling it can be a challenge to route the new dedicated branch circuit cable(s) from the parallel runn... | |
| Isolated ground in dedicated room/new construction? EDIT: Also avoid running the three dedicated circuits parallel to other branch circuit wiring. Should read: Also avoid running the three dedicated circuits parallel in close proximity to other branch circuit wiring. Especially LED Lighting ci... | |
| Isolated ground in dedicated room/new construction? Room will have have 3 dedicated 20 amp home runs for the system using 10 gauge 10/2 romex with ground, terminating with PS audio IG 120v outlets. terminating with PS audio IG 120v outlets. @frym Did you run that by the builder’s electricia... | |
| Dedicated circuits where to buy a magnetic breaker? You won’t buy em for your electrical panel... Only T-M, Thermal-Magnetic, breakers are available. The Thermal protection unit of the breaker is for overload protection of the branch circuit wiring. The magnetic ... | |
| Dedicated circuits @immatthewj Myth is a breaker will trip when the current passing through the breaker reaches its handle rating. NEMA requirements says a breaker must trip in less that one hour if overloaded 135%. It also says a breaker must trip within 2 minut... | |
| Dedicated circuits if a 15A breaker was in front of a circuit that was made of 12-2 Romex and 20A outlets, wouldn’t that be safer? I mean, the 15A breaker would trip way before the 12-2 or the 20A outlet got hot enough to catch fire, right? No you can not put a 2... | |
| Dedicated circuits Current doesn’t always go up when voltage goes down, it’s a little more complicated than that. That is true. For AC induction type motors if voltage goes down due to Line voltage drop, current go up. Not so for audio equipment power transforme... | |
| Dedicated circuits FWIW: jea48 3,919 posts 06-07-2022 at 08:04pm @kijanki +1 Please explain what happens if the power transformer’s secondary winding voltage is lower feeding the rectifier, due to a quick AC mains VD event, and the electro... | |
| Why and how grounding is needed for Inverters @4krowme Thanks for the kind words. Jim | |
| Voltage conversion of Accuphase A-65 or A-70 Don't know if thread will help. https://forum.audiogon.com/discussions/voltage-conversion-of-accuphase-e-650 @imhififan May be able to help you if you can post a picture(s) like others did in the above thread. | |
| Why and how grounding is needed for Inverters @neo_the_one The model you have posted is the one that got me confused. It does have a separate grounding post that the inverter + charger does not seem to have. I could not find anything related to grounding in the invert + charge model’s man... | |
| Why and how grounding is needed for Inverters @neo_the_one, I took the time this morning to look up the unit, I believe, you are buying. Its wiring scheme is different than the 3000W unit video above. Here is the manual for this 2000W unit. (Click on the Link below.) https://www.ren... |
