| Single Point Ground First, you need explain what your understanding of a single point ground is?If you are going to have two dedicated branch circuits installed, and they will be installed per NEC and AHJ (authority having jurisdiction) in your area, you will end up ... | |
| Rel Stadium 3 Humming Motionpicture007,Did you try using a ground cheater on the sub's amp power cord plug? | |
| So Much "Harshness" Mrtennis,I bet you would be hard pressed to find anyone with totally analog gear system that complains about harshness.20 years ago we did not have computer based electronics that cause the hash on the AC line as we do today. Damn near every appli... | |
| So Much "Harshness" As for digital, in many cases, harshness is caused by EMI/RFI from the power supply of the digital equipment itself. In most causes the use of a good shielded power cord will solve the problem. Ics can play a roll as well. Airborne RFI can also en... | |
| Isolation Transformer - Use with Cheater Plug 02-22-09: HhawkForgot to say that I do have Directv and audio is connected to the preamp via RCA jacks. So maybe a RCA ground isolation device is what I really need.Could very well be the source of the ground loop hum....For lightning protection t... | |
| Isolation Transformer - Use with Cheater Plug A balanced power system is still a grounded AC power system, (60/120Vac). True both 120V legs are ungrounded with a reference from each leg to the grounded neutral of 60V. The neutral is still connected to earth ground per NEC Article 647.~=======... | |
| Isolation Transformer - Use with Cheater Plug 02-21-09: NgjockeyAccording to code, the ground is not isolated by the iso and is continuous. The positive and negative are isolated.And just to add.... For isolation transformers less than 2 KVA, if memory serves me right on the size, the safety ... | |
| Directional fuse and integrated IEC outlet Al,I for one have not experimented with fuse tweaking in any of my audio equipment. My concern with audio grade fuses is how accurate is the fuse to blow under an overload condition. I have not read any actual testing of such. Of course at 30 buck... | |
| Isolation Transformer - Use with Cheater Plug If you plug equipment into a isolation transformer like a Tripp-lite using cheater plugs, do you still get the shock benefit?You bet! You could receive an electrical shock if a ground fault condition were to exist under the right conditions.(The o... | |
| advice re: hum and passive distribution bars. Just to be certain I understand the bare wire should attach between and connect to both the receptacles by just pressure after (tightening back down) onto the bottom metal body work ( supporting straps) that has the holes used to screw duplex into... | |
| Directional fuse and integrated IEC outlet Al,Solid core wire is directional. The late Bob Crump. | |
| advice re: hum and passive distribution bars. One other thing you might try.....I assume the two dedicated circuits and duplex receptacles are somewhat next to one another. A few feet apart at most.You will need a length of bare #12 or #14 copper wire. (Bare solid wire from a piece of Romex w... | |
| Directional fuse and integrated IEC outlet Just guessing, the direction would be from the incoming Hot to the load, the power transformer.... | |
| Would it hurt Elite receiver to run 4 ohm speakers Yes, the Amp could see a load impedance as low as 2 ohms from the nominal 4 ohm speakers..... | |
| Dedicated Lines Bflowers,True dedicated circuits do not share the same cable or raceway.RFI/EMI can transfer from conductor to conductor when sharing the same cable or raceway, (conduit). Also induced voltage from one circuit will transfer from one to the other. ... |
