Has anyone tried these stunning new CPT power cord?

grannyring,

Going a make a Deulund PC for my CPT and upgrade the internal duplex wiring. Is it necessary to double up the ground if I double up the neutral and live so that I’m not restricting power going into the CPT 1200?

Planning on burning in on my cable first before upgrading internal wiring.

Has any of you added a DC blocking scheme to your 1200 or 1800 and if so, do you have any pictures on how it was integrated into the unit? Mine does buzz occasionally and this circuit could make a noticeable improvement for sure. Maybe I should opt to have my Deep Core delivered verses a refund?  

Thanks,

Wig,

Double the ground also.

The populated DC blocker needs to go between the IEC/breaker and the transformer input leads. I don’t own this unit so without it right in front of me I cannot give specific instructions. Generally you would do this....

The board has a live, neutral, and ground connection on the input and output of the board. Six total connection points. Three in and three out (L,N, and G). No place for mistakes here as you have high voltage and can hurt yourself and/or unit!

I really need to see to see how it is wired and these are general ideas only. Like to see, up close, the IEC and on-off breaker wiring both to each other and to the tranny close up.

The input would normally be fed the Live lead from the breaker. The breaker/on-off switch will have two black wire leads on it. Remove the black live wire lead connected to the tranny input and as this lead will soon be connected the Live output on the DC board. You now run a 12 gauge wire from that same breaker tab to the Live input terminal on the board. The IEC ground goes to the G input terminal on the board.

That black lead out from the input to the tranny now goes to the L terminal on the output of the DC blocker board. There will be a neutral wire also going into the tranny input side with the black wire you just hooked up to the L output on the DC board. It is most likely twisted with the black and perhaps white in color. That white wire now gets connected to the N on the DC output terminal. That now naked tab on the switch where the white wire was needs a 12 gauge new run to the N on the input of the DC board. Now only output ground is left on the DC board.

You really need to know what to look for and plan carefully based on how this unit is wired. Again, my points above are my general guidelines and will help you as you look into the unit live and unplugged 😊

You may want to let a professional do this.

@ grannyring

Thanks and just sent you a PM.

For those interested I added pics and a description of my mod to the Balanced Power Technologies isolation Balanced transformer. It is very much like the CPT units. Look under the notes on the BPT unit and the pics are all at the end of the picture series.....last 5 pics.

It was very, very tight behind the outlets and I think your CPT units have much more room there. Hard to pack all I had into that cramped space.

I did the following....

Added a DC blocking circuit

Wired with the new Duelund 12ga Polycast 600v wire - home run direct wiring to each outlet

Added Porter Ports upgraded outlets

Treated all connections with Perfect Path Contact enhancer

Added Audience XO caps across each outlet for filtering

Added a nice Furutech IEC

Installed new 2 pole circuited breaker

@grannyring..........

I just looked over your system, very nice indeed. I am very impressed with your DIY work, very professional. I could never do that and make it look good. You get the hat tip of the day.  I was hoping all you guys would get an early Christmas gift by way of a refund.  Very sad.
