GFCI 20 AMP breaker tripping

From the main house there is a 100AMP service to a shop about 160 ft run there is a 10-2 wire from the electrical panel in the shop going to an outlet that has a 20 AMP outlet with a 20 AMP GFCI breaker this is the only outlet that is on that breaker however anytime I use a tool such as my miter Saw or my welder it seems that the breaker keeps tripping I donít remember what the electrician said about the 160 foot run but he did say it was an upgrade to what normally would be in a 100 amp service box due to the length of the cable to run from the house to the shop Any advice on what could be the cause or how to resolve this issue

A GFCI does not trip on overcurrent, so either the GFCI is defective or both of your appliances have a leakage path for the current. Do you have another GFCI where you can test the appliances for proper operation?

Gfci

I do not have another outlet that would work however I do have another 20 AMP GFCI breaker I can switch it out to see if that solves the problem

This one does, it's a 20 amp GFCI breaker, not a GFCI receptacle.

Thanks for the update Casual Joe. I misunderstood the configuration.
