is it okay if I "twist" my ground wire around mains wires. The ground wire is going to the ground-loop breaker.1 end of the ground wire is connected to something like this: http://www.dse.com.au/isroot/dse/im...ucts/p4850.jpg.
The other slots are taken up by the live, neutral, AC ground and B+. Another 4 is taken up by wires to connect to a motor run cap.
After the ground loop, the ground wire goes nowhere else.
any comments?
Follow Ups:
When you say ground, are you discussing the SAFETY Ground or the circut Common return? Since the SAFETY Ground wire of a 3-wire power cord is already in close proximity to the mains wires throughout the length of the cord & building wiring, similar proximity for the short few inches within a chassis (to chassis connection) should make no more differance = no twist needed. If you mean circut Common, that return buss should be kept away from any & all voltage-carrying wires. AND circut Common should never be directly connected to the SAFETY Ground; SAFETY Ground & circut Common should each have their own separate chassis connection points, otherwise jacks, terminals & controls would be excluded from the SAFETY circut = Danger. As Aretha Franklin sang, Think!

So your answer is in my 1st reply = do not twist power supply negative around B+ wire or AC Mains wires. AC must flow in BOTH wires for a twisted pair to achieve a null effect (as with heater supply). And BTW, your initial included web addy does not work. Per clarity & confusion avoidance: Realize the only operational requirement for an audio circut to have an Earth Ground connection is the SAFETY connection. Otherwise, there is NO actual Ground in the circut; such nomenclature is an archaic carry-over from the 1st early days of crystal Radio in whicn an actual Antenna circut connection to Earth was neccessary to boost weak signal strength of passive components. The Old Timers erroneously & unneccesarily continued to refer to such current returns as *ground* when active devices (tubes) became available, because such was their habit. Today, circut Common is a more relative term towards understanding actual circut operation. Hope this helps & have a bad weekend (where *bad* in this instance actually means a good time!).
how about the circuit ground/common being right beside the AC mains wires?the AC mains wire are twisted together and I'll use cable ties to hold the circuit common wire?
re-route the Common buss? I'd sure try to place it further apart from the AC Mains entrance to avoid posible Hum/noise pick-up. If this is not a DIY build (where you can pre-select your layout), but instead a commercial assembly, & you experienced no problems prior to weekend-EE power cord mods, then respect the original design.
