Not really
It only turns Normal type moves in to Electric type moves for the remainder of the current turn, which means means you won't be pulling off any Electric type Giga Impacts, and Giga Impact sucks anyway. It can be used to get Motor Drive boosts, but if the opponent doesn't use a Normal type its useless, and in most cases will just end up as a waste of a moveslot, Normal type attacks not being that common.
To sum it up, no, I don't recommend using it for Electivire, or any Pokemon really.
