Narrative:
Airlines inspector phoned me to inform me that aircraft X had a ground interrupt because of a circuit breaker/or breakers that was not reset from overnight maintenance. I worked this aircraft on overtime; it is not my normal aircraft assigned. I am not totally familiar with the B777 aircraft. I asked for someone to back check me to ensure tasks were performed correctly prior to aircraft release. Unfamiliar with all the lockout procedures on a 'B' check. Do not usually work 'B' check aircraft or the B777 aircraft. Asked for assistance to be back checked.
