Any intentional use of power should never use the ground path. The grounding conductor is used for grounding of any metal parts (safety ground) and surge suppression.

Most surge suppressors have 3 separate surge suppression devices in them. One protects against line-to-neutral (L-N) surges, one protects against line-to-ground (L-G) surges, and one protects against neutral-to-ground (N-G) surges. Without the ground, the L-N protection should still work, but the L-G and N-G will not.
