Chris,
I haven't made any ribbon power cables but off the top of my head my concern would be proper insulation for 120V and then how do you fit and secure the ribbon in the AC connector?
I do use Elrod power cables, which are ribbon, but never cut one apart to see the construction.

I agree, trekpilot5.2. A number of DIY AC delivery designs may sound good, in part due to cutting corners on safety, and there's nothing one can do to stop a person who chooses to build an AC device that's unsafe, but it's the responsibility of other AA Inmates to caution others about a design that could result in a catastrophe. No matter how careful a listener may treat a dangerous AC device, there are still potential hazards that might occur at some point regardless of how careful the device is handled, including a future end user with kids and pets who might find a questionable AC design at a yard sale when the DIY builder is no longer around to warn them about a potentially dangerous AC delivery device.
Hi all,
Sorry for not better clarifying; I had NO intention of using packing tape as the insulator for a power cord; I simply used that for the speaker cables, given its ease of application and the low voltages involved.
I was wondering if it might be possible to make a power cord using the left-over ribbon conductor, if it were insulated with appropriate heat shrink rated to 600V, or similar. Would this still be a bad idea?
Thanks so much,
Chris
you dont think it would throw 15A breaker if it dead shorted? It would. Im not big on the OP choice of double sided scotch tape though.

A dead short should cause the breaker to trip. But the bigger danger is in using unrated and imperfectly applied insulation materials resulting in a current flow between the conductors. Not a dead short, but enough to generate heat, causing further and escalating breakdown of the insulation, and in the end, a fire. Ribbon material may be great for interconnects and speaker cables, but is a very risky endeavor for DIY power cords, IMO.
If you have no idea what the voltage rating of the insulating material is.. You really cannot use it.
I have never seen the voltage rating listed of 'double sided Scotch tape'. Nor of 'generic packing tape'.
