I've actually already asked ERICO about the application, i asked them if they were rated for the use and they without hesitation said yes and that they are rated for(or above) the current and temperature of the wire used with, as you would probably assume.
to the point of disconnecting wires, i was thinking the application may be used for inline splices, like long runs, or hard pulls, cadweld and heat shrink, i figure that would be pretty bulletproof/reliable. not that compression isn't great, but you know, in the name of "better" and "why not".
thanks guys
