| Measurements for a dedicated line N-E volts 00 with the microwave on or off Those figures were all based on using the KAIWEETS tester. I have other DMM’s which are much more accurate. Since I’m discovering my readings are now in the mV range, I won’t be using the KAIWEETS teste... | |
| Measurements for a dedicated line @jea48 I completely understand VD on hot and neutral. Thanks, but no further explanation is needed on that. My curiosity was always with the N to EGC. That’s where I’ve been confused all along. I’ve never paid much attention to that measurement.... | |
| Measurements for a dedicated line (I assume the audio branch circuit is 2 wire with ground...) Correct. It’s still not clicking in my brain what you’re trying to say about voltage drop across the neutral and EGC. No offense, but if I already have a low impedance EGC, why shoul... | |
| Dedicated 20 amp circuit. 10/2 or 10/3? I have three dedicated circuits to my audio area and all three are on breakers next to each other on the same side of the panel. Since this wasn't mentioned; this means that 2 of these circuits are probably on one 120 volt leg of a 240 volt se... | |
| Measurements for a dedicated line Are you sure you have an Equipment Grounding Conductor at the outlet? 100% most definitely; on both outlets being discussed. I can take my multimeter and read 121.6 volts across the hot and neutral (no load), and the exact same voltage is measu... | |
| Measurements for a dedicated line AC voltage, harmonic distortion and line frequency are all measurable. If there is a difference between night and day listening, and it's related to power delivery, we should be able to measure it. Personally I think some of this is psychological.... | |
| Measurements for a dedicated line I too have whole house surge suppression (never lost anything from storm damage the entire time I lived at this location - going on 23 years now), but since I have so much money wrapped up in audio, video and AC isolation and filtering gear, I som... | |
| Measurements for a dedicated line I have a dual gang countertop outlet that has a GFCI outlet in it. It is then connected to, and protects the outlet right next to it. The microwave is across the room, and isn’t within 6 feet of the kitchen sink. When I first moved in in 2001, I i... | |
| Measurements for a dedicated line @erik_squires Good point Erik. I have a Panini maker which is rather light in weight, and easier to relocate vs. my pizza oven or microwave. It consumes 11.8 amps (the pizza oven consumes 11.5 amps). I plugged it into my 10 AWG main audio feed AC ... | |
| Measurements for a dedicated line Using the KAIWEETS KM117B Socket Tester (the one @erik_squires linked), I took some measurements around my home: My pizza oven consumes 11.5 amps during operation (measured using my Amprobe ACD-10 TRMS-PLUS meter). With the oven off, AC volts ava... | |
| Measurements for a dedicated line Another plug in voltmeter that I really like is the Kill A Watt EZ meter. It measures a lot of things, but the voltmeter portion (which reads in tenths) is extremely accurate. Kill-A-Watt(Tm) Ez | |
| Shielding components from EMI/RFI... Help please @bryoncunningham You have a very nice clean rack of equipment. Many of us are trying to reach nirvana with our audio systems. I applaud your endeavor of re-engineering some of your components to resist EMI/RFI. Many would not bother with this. Wha... | |
| Measurements for a dedicated line I received the test meter today that @erik_squires linked. Right off the bat I would say I’m impressed by its performance. One thing I look for in an AC voltmeter is how quickly it can measure and display voltage drops or variations. Even at ear s... | |
| Measurements for a dedicated line @erik_squires >>>once current is flowing through your circuit an excessively high N-E indicates excess resistance on the neutral.<<< OK, this is starting to make a little more sense now. A device on the circuit being tested... | |
| Measurements for a dedicated line @erik_squires Since I do pay a considerable amount of attention to power quality, bonding and grounding (bordering on OCD), and because of your provided link, I have now ordered this tester (mainly just for the N - E figure). I'm not sure I'm goin... |
