Freezer dedicated non-GFCI receptacle in basement

A dedicated circuit may be a good solution, but whether a non-GFCI receptacle is permitted depends on the exact location and the applicable BC Electrical Code requirements. A dedicated circuit alone does not automatically make a non-GFCI receptacle acceptable. I recommend having a licensed electrician inspect the basement and determine the safest code-compliant solution for the freezer.

The micro electronics in a gfi protect you from a possible lethal shock ( often in damp area , basement or outside ) . If appliance is safe no problem , if gfi ( regulations for this style plug is to prevent problem shock ) keeps turning off circuit you have a problem that must be fixed for you safety . Older style breaker panel gfi like breakers did not always give proper protection , some time if you stirred a pot on a stove and you touched a sink you could get a shock , no gfi to protect you . The surface element was leaking and if tested you got a voltage to ground , not enough to blow fuse but enough to cause shock , had to replace element and check all others for problem . Hope this helps you to understand your question .

Yes, depending on the specifications the manufacturer states in owners manual. If that isn't followed, the warranty is void.
