Matt;

The General Motors HEI ignition systems reportedly can achieve 45kv so
silicone jacketed HEI rated spark plug wire should be more than adequate on
an MOT system. I think most varieties should be able to withstand 20kv at
least.

BTW, Walmart sells a high performance, silicone spark plug wire kit; About
30' bright orange 8 mm silicone cable. About 14 gauge copper conductor.
Last time I bought one of these kits I paid $8.00 American. The wire is
super flexible, solders well, looks good and the spark plug boots make nice
covers for where the cable attaches to the NST HV bushings.

Hi All

I have acquired some automotive copper-cored HT cable for MOT "hot side"
interconnects.  Does anyone have any ideas about the insulation rating of
this stuff?  There are no markings on the cable (should be illegal,
grumble, grumble).

The cable has an OD of 6.7mm/0.265" and, as well as I can measure, the ID
of the insulation is 1.0mm/0.039".

Although I have no intention of being near it when it's live, I can get
silicone or PTFE sleeveing to slip over it if anyone things that the rating
would be too low for TC work (assuming up to MOT four-pack a la Greg
Hunter).

Cheers

M
