I had a licensed electrician add a dedicated sump pump circuit in our unfinished basement. . He installed a GFCI. Electricians debate this all the time. Look it up - I'm no expert on this, so enlighten me, someone.
A failed sump pump can be a nightmare situation.Ankle deep standing water in a basement after a sump pump fails is no picnic.But what if that standing water is energized and capable of delivering a lethal shock?

"Until about 2008, the NEC has a specific exception for sump pumps. Most sump pumps are installed in unfinished and finished basements. The exception provided that a sump pump did not need GFCI protection provided it was on a dedicated circuit with one outlet. This exception was removed
The latest 2020 edition of the NEC does not have this exception and has expanded the requirement for GFCI protection to include both finished and unfinished basements. Hence, the usual location of a sump pump in the basement would require a GFCI protected circuit."
