Need Earth Ground Without Drilling a Hole

after about a minute it does.

if the live shorts to the box hundereds of amps will flow.

the earth connection has to keep the box at a safe voltage until the breaker opens.

Yeah.... that breaker needs some heating time... It's a thermal mechanical device. Meanwhile current runs high. I thought shooting for a 15amp continuous fault current earth ground connection might get me in the ball park. Hopefully the breaker trips before the earth ground connection burns open due to contact resistance.. D from BC

level,

It is also easier to visually determine the quality of the ground connection where a mechanical type solid connection eg. stud/screw, shakeproof washer and nut, is used. A soldered joint is harder to perform properly and the quality of connection is not easily determined by visual inspection. For safety ground connections in particular, I think you will find that a mechanical connection is specified as the standard by most safety authorities.

I have seen quick connect (QC) tabs and push-on terminals used for the safety ground connection on domestic appliances such as fridges, but I am not sure if they are acceptable unless the cable end connector is a locking type which cannot dislodge due to vibration or other accident.
