| Line fault at the outlet -- do I need an electrician? Guys, way to much time has been spent on this thread about the OP measuring a difference of potential, voltage, of 4 volts, from the neutral to the equipment ground contact on the receptacle outlet. His biggest problem is reversed AC polarity he ... | |
| Line fault at the outlet -- do I need an electrician? Correction: jea483,299 posts 03-22-2020 2:57pm Also as I said previously. 1) VD, (Voltage Drop), on the neutral conductor due to the connected load on the branch circuit.2) An induced voltage that is/may be created by the hot and neutral curren... | |
| Line fault at the outlet -- do I need an electrician? hilde45 OP As far as finding the outlet closest to the panel is a bit tricky, as the wire which feeds things disappears into the ceiling and I'm not sure where it goes first. I'm sure where the 3rd, 4th outlets are, but not the 1st, 2nd ones... | |
| Line fault at the outlet -- do I need an electrician? almarg9,456 posts 03-22-2020 2:11pm @Hilde45, when you measured the 4 volt difference between safety ground and the miswired "hot" terminal on the outlets was some or all of the equipment plugged in at the time? If so, I think it would be worthw... | |
| Line fault at the outlet -- do I need an electrician? hilde45 OP283 posts 03-22-2020 12:14pm Thanks, Jim. Later today, I will probably try this. Or tomorrow.Before I proceed -- I want to be clear that so far I have tested multiple outlets on this daisy chain -- they all read as reversed.I ... | |
| Line fault at the outlet -- do I need an electrician? @ hilde45 OP Ok. | |
| Line fault at the outlet -- do I need an electrician? @ hilde45 OP As djones51 said, start with the wall duplex receptacle you tested that has the reversed polarity. (Hot and neutral wires reversed on the outlet device.)Make 100% sure the breaker that feeds the outlet is turned off. Plug a lamp into ... | |
| Line fault at the outlet -- do I need an electrician? heaudio123135 posts 03-20-2020 8:58am "3) Measure for voltage from the equipment ground contact to the neutral contact. The neutral contact is the larger of the two slotted holes on the outlet. Make sure the two DMM probes are making good... | |
| Line fault at the outlet -- do I need an electrician? hilde45 OP269 posts 03-20-2020 7:26am @bryhifi I have a digital multimeter. I use it to test car batteries. I suppose I might use that, too, no? In any case, I can get the three prong outlet if necessary. The DMM will work just fine.1) Set the m... | |
| Surge protector vs wall debate for amps @lowrider57 The Wiremold strip shown in the Link you provided does not offer surge protection. It is strictly a plug strip.Jim . | |
| Beware of NAD M3 Fire Hazard pwb OP9 posts 03-15-2020 10:01am Thank you everyone for the useful information. I guess I will just have to take the loss and move on. I will never purchase an NAD product again. Anyone have a recommendation for a good integrated under 2k... | |
| Beware of NAD M3 Fire Hazard almarg9,445 posts 03-15-2020 11:20am I noticed the vent cap on the other cap did not look like it was affected by the event. It doesn’t look like there is any bulging in the top vent cover. Wouldn’t the shorting diode have affected that cap as we... | |
| Beware of NAD M3 Fire Hazard heaudio123 Said: Could be anything, but a shorted diode in the bridge passing AC and cooking the capacitor would be my guess. jea48 response: Wouldn’t that cause a high current load on the secondary winding of the toroid power transformer causing ... | |
| Beware of NAD M3 Fire Hazard https://ibb.co/T1VBM5G I’ve never seen the top vent of an electrolytic cap blown off like the one in the photo. That’s just plain scary! heaudio123 Said: Could be anything, but a shorted diode in the bridge passing AC and cooking the capacitor wou... | |
| Low hum from amp @ greh OP If you had said the hum sounded like 120Hz then that would indicate an electrolytic filter cap/s in the DC power supply.60Hz..... My first thought would be a ground loop hum, except where you said the hum doesn’t start until after 30 min... |
