Which connection looks best and more stable

[xboxhaxorz]

Obviously the ceramic connectors will be more expensive which is not a real issue, i am simply looking for the best connection

The ceramics do take up a bit of room compared to the other connector as well

For some reason, im favoring the 2nd photo with the heatshrink tubing

Re: Which connection looks best and more stable

The one with the least contact resistance, safest, meet compliance requirement. How much current will be flowing through the circuit? Any compliance and inspection required?

We are trying to meet UL/ CSA requirements but we are not going for inspection

It will have 110v per line ie; 220v at approximately 2 to 3 amps

different tools for different jobs,
ceramics are for high temperature stuff - used with heatproof wire obviously.
halogen lights are a good example.

Re: Which connection looks best and more stable

A soldered connection is always superior to screw terminals, for vibration and temperature, resistance, corrosion etc. but is more work.
Usually the heatshrink is CSA/UL rated for 300V, or a final wrap of electrician's tape (one layer per 300V minimum) is good. You can buy thickwall heatshrink comes/with hot glue inside, for a totally waterproof seal. If this is a high temp >105C application then special heatshrink is prob. needed.

P.S. - I hope you aren't using green wire for power. That would be trouble.
I had a colorblind electrician wire up a motor starter panel. He confused red and green, so he connected one-phase of 480V to chassis, and I caught his mistake but it would have been bad.
