Also how long is this cable of yours? 2AWG is roughly 35mm2 which I do have experience of moving around and I know its no joke.
Keep pushing on, things are gonna get better.

It is single phase which is why, the cable offers 4 Cores. The Crouse Hinds Barrel is indeed metal in which, you have the option to ground it or not. Crouse-Hinds is popular in the commercial industrial market in the States. https://www.eaton.com/us/en-us/company/about-us/our-heritage/crouse-hinds-series.html



I own two systems. There is no way to operate my larger sound system on standard US consumer AC receptacles without a significant drop in voltage and, constantly tripping breakers. There are just too many amplifiers which equates to a lot of current required.


The smaller sound system will perform fine using standard consumer receptacles for I am using a few amplifiers. Standard US Home consumer receptacles are 15-A and, 20-A. In the Metropolitan areas the voltage will exceed 125 volts whereas, rural areas you may not see anything higher than 117 volts. You will need to share the circuit with something else (Refrigerators, Air Conditioners, Microwaves etc.) so, you can expect voltage to be lower than what is listed above.


The cable is short enough to extract 100 amps per leg under 120-volts with only a 0.8% loss which far exceeds NEC requirements. NEC requires the voltage should not offer greater than a 5% loss. I follow the old fashioned method, keep the power cables short as possible and use long runs for everything else. 35 mm2 weighs a lot and, maneuverability is very minimum. But, the performance it provides is well worth the trouble.


Best Regards,

Would love to see your sound system Elliot. Have you any pics?

So you use split phase (new to me, https://en.wikipedia.org/wiki/Split-phase_electric_power ) So do you run your amplifiers on 240V then?

No pictures. That was never my style. I will post photos of the internals of an amp I recently purchased time to time or parts to add on to the sound system. That's basically it.

They are operated on 120 volts. The only amplifiers I own that are capable of 240 volts (or 208 single phase) are the Crown MA 5000s. However, they are used on 120 volts as well. I picked up a Bell Mixer (Made in Germany) years ago that needs 240 volts to operate properly in which, I just use a step up transformer.


120 volts is standard in the States for the majority of buildings. You may find a few buildings that offer a combination (208, 240, 480) which, are aimed for more industrial machinery. The majority of residents have 240 volts in their homes. Our electrical system is setup so you use the neutral and one hot to attain 120 volts. So it is 240 volts total or 120 volts per leg.

Red (Hot) & Neutral = 120 volts

Black (Hot) & Neutral = 120 volts

Black & Red = 240 volts

Green = GND

So presumably at the end of your cable you split to red phase and black phase, each at 120v but different phases? And run half your gear on each?

 The image below will give you an idea how a typical panel is wired in the United States. In the event 240 volts is required, you would use a Dual-Pole Breaker which is pictured on the left. Single-Pole Breakers are 120 volts which, are listed on the right. As this Panel does not offer a service disconnect from the feeder, this panel would be typically found in Apartments where you need Remote Panels for each Tenant.






Homes will have a service disconnect in the Panel with the feeder being sent directly from the Utility Pole into the Panel.




Best Regards,

The Current Transformers arrived for the Westinghouse Meters. This should (hopefully) complete power supply upgrade. I can now move on to something else...



Getting ready to clean out the dust out of on my old California Instruments Voltage Regulator. I purchased this used 30 years ago from a pawn shop for $50.00 due to staff having no idea what it was. I bought it to maintain constant voltage for my audio processors. It can offer a constant 15 amps of current RMS @ 120 volts and, weighs as much as a Crown Macro-tech 5000vz. With the 2 AWG Power Cable upgrade, it will be used more as an Isolation Transformer to reduce noise (Ground Loops, EMI, and so forth).

make sure you plug it in with gold plated mains plugs and only use audiophile grade cable in your system, or you won't hear any difference!
