| Lets talk dedicated lines @ volumizerI am not sure exactly what good is the testing that was done in the link you provided.The white paper did not address anything about a voltage that may/will be induced onto the equipment grounding conductor using the 12/3 with ground ca... | |
| Voltage question winoguy17 OP655 posts 03-02-2020 6:28am As stated in the OP ,its rated 100v. If I do pursue this I would probably look into stepping down the voltage. Where is a good place to look for one? Thanks again. I would first check the AC mains voltage... | |
| Voltage question Would a component from Japan that is rated 100 volts be safe to use here on 110-120 volts, Safe? That's not the problem. The problem is you will be feeding the piece of equipment at a much higher voltage than the equipment was designed to be oper... | |

| Equi=Core Hum & Other Issues Lowrider57 said: This leads me to the question; can DC offset be measured by the electrician either at the service panel or the wall receptacles? DC on the AC mains can be measured at either location. In your instance you want to measure it at the... | |
| Equi=Core Hum & Other Issues @lowrider57 Square D QO. Good Choice.No doubt he carries a Square D QO 120 breaker in his service van. Still wouldn’t hurt to tell him the breaker is a QO 120 breaker. Only a Square D QO breaker will work in the panel.No need to have the audio equ... | |
| Equi=Core Hum & Other Issues @lowrider57 For some reason the above post, I originally posted last night, was corrupted after it looked fine after I posted it. The post this morning is the same without the corrupted part as seen at the top sentence of the post last night. I th... | |
| Equi=Core Hum & Other Issues lowrider57 OP3,544 posts 02-26-2020 4:06pm To power up the system, I turn on the Equi=Core, then the panel breaker trips immediately. I used to repeat this procedure but the panel tripped every time I turned the EQ on. @lowrider57 That tel... | |
| Equi=Core Hum & Other Issues CORRECTION: jea483,262 posts 02-25-2020 9:25am @ lowrider57 Stop using the Equi=Core..... Get it repaired.You need to hire an electrician to have the 20 amp breaker in the electrical panel replaced. That is a must!... Repeated tripping and reset... | |
| Equi=Core Hum & Other Issues lowrider57 OP3,542 posts 02-25-2020 8:45pm Hi Uber. These problems came out of nowhere. Like the circuit breaker tripping, there’s no way the EquiCore is overloading a 20A circuit. That’s why I think the electrician should have a look first. @lo... | |
| Equi=Core Hum & Other Issues @Al, (almarg),Thanks for the kind words.I find it’s best just to ignore his posts.Jim | |
| Equi=Core Hum & Other Issues lowrider57 OP I think I should call the electrician to address the breaker situation. The 20A breaker being tripped at every powerup has never happened before this week.Would he be able to measure DC offset? Good chance the electrician will look... | |
| Equi=Core Hum & Other Issues @ lowrider57 I agree with testpilot and lak , send the unit in for repair. As for measuring DC on the mains. You cannot measure DC on the mains by connecting a regular DVM directly across the AC mains at the wall outlet. You would need to connect ... | |
