| On one leg or two legs? Even when just a power amps connected to the speakers, and nothing else connected to the amps, and with grounds lifted on both amps with a cheater plugs, still I hear faint hum (much louder with no cheater plugs).I have tried everything:Unplugged ... | |
| On one leg or two legs? Hevac1,It couldn't hurt if Maril555 moved the projector branch circuit over on the other leg, L2, of the sub panel. Might even help in balancing out his main electrical panel.Will that solve his hum problem? No, jmho.As for the total load that is ... | |
| On one leg or two legs? I will have to look at that screw when I get home, but what are you thinking about?01-30-09: Maril555Looking again closely to the picture it looks like the screw is used to connect the left side neutral bar to the cross tie bus to the right side n... | |
| Grounding A Preamp Licoricepizza, Question: If you select, say, CD for the listening input on the preamp, is the buzz present? If not and it is only present when the preamp listen selector switch is set to phono..... there may very well be a problem with the preamp. | |
| Grounding A Preamp 01-30-09: LicoricepizzaThe preamp also has a 2 pronged plug. The buzz is coming from the speakers, and is volume dependentWell if I understand you correctly at on point in your trouble shooting you isolated, disconnected, everything from the input... | |
| On one leg or two legs? I also see one orange 12 awg. cable entering the sub panel- the black (hot ?) wire is not connected to the breaker, terminated with the cap, the white and bare ground are connected to corresponding bars. What's that about, I don't know. 01-30-09: ... | |
| On one leg or two legs? Maril555,Are the 4 single pole breaker that feed the #10 wire branch circuits 30 amp?If so that is a no no... Should be a max of 20 amp.If the receptacles are 20 amp then the breakers must be 20 amp.That would not cause your problem though.... | |
| On one leg or two legs? Maril555,Looks ok to me..... I see the feeder equipment grounding conductor is part of the feeder cable. I assume it connects to the ground bar in the main electrical panel. Sub panel looks fine. Branch circuits are fed from L1, leg, of the panel.... | |
| On one leg or two legs? 1. When everybody says "isolated ground" does it mean ground bar in the panel isolated from the metal enclosure?I don't know about everyone else.... But that meets the definition as far as NEC. Then from the isolated ground bar an insulated equipm... | |
| Grounding A Preamp 01-29-09: LicoricepizzaThe TT does have 2 prong plug.How about the NAD preamp? To this untrained ear, it sounds like a 60Hz buzz, like you'd get from a fluorescent light, or a wall-wart transformer.Is the buzz sound being heard from the speakers?O... | |
| On one leg or two legs? I have licenced electrician to install separate panel with five dedicated lines connected to it:A sub panel fed from the main electrical panel.By chance do you know what size wire he used to feed the sub panel?I assume the electrician fed the sub ... | |
| Grounding A Preamp I have a NAD 1155 preamp with a nasty buzz in the phono stage. It's not a phono grounding issue, because I checked that.How did you check that?If you disconnect the TT from the NAD (ics as well as TT ground wire) is the buzz still present? Should ... | |
| On one leg or two legs? NEC Codes might have been updated in the past few decades, but back in the 70s and 80s, the specs i noted here were acceptable.... passing inspection everytime. I've never been red tagged following an inspection... well, when I was a practicing sp... | |
| On one leg or two legs? Blindjim, Did you read my post, (01-26-09: Jea48)? 01-25-09: BlindjimThe length of dedicated ckts, one to the other, is superfluous. Arbitrary. Only really extensive runs of #12 romex (which is likely what will be used, unless otherwise specified)... | |
| On one leg or two legs? Blindjim,Just curious.... Why did you spend big bucks for Shunyata Python VX and Shunyata Research Taipan helix Alpha power cords? I believe the wire gauge in the cords is equivelent to #10 awg. For the length of the cords you could of more than l... |
