Narrative:
Taxiing to the gate the first officer set 5000 ft into the altitude alerter anticipating the phl 6 departure. We were cleared to our destination and told to maintain 4000 ft. During the brief for takeoff, I (the captain) briefed 5000 ft off of the alerter and neither of us checked the clearance as written by the first officer. Upon leveling at 5000 ft, the controller queried as to our cleared altitude and we realized our mistake though there was no traffic conflict. After discussing the problem, we decided that setting an outbound altitude during taxiing in is not only illegal but unsafe. We also discussed our clearance referencing the original copy during the brief.

Title: A BE1900 FLC CLBS TO 5000 FT BASED UPON THEIR ALT ALERTER SETTING BUT HAD ONLY BEEN CLRED TO 4000 FT NW OF PHL, PA.
Narrative: TAXIING TO THE GATE THE FO SET 5000 FT INTO THE ALT ALERTER ANTICIPATING THE PHL 6 DEP. WE WERE CLRED TO OUR DEST AND TOLD TO MAINTAIN 4000 FT. DURING THE BRIEF FOR TKOF, I (THE CAPT) BRIEFED 5000 FT OFF OF THE ALERTER AND NEITHER OF US CHKED THE CLRNC AS WRITTEN BY THE FO. UPON LEVELING AT 5000 FT, THE CTLR QUERIED AS TO OUR CLRED ALT AND WE REALIZED OUR MISTAKE THOUGH THERE WAS NO TFC CONFLICT. AFTER DISCUSSING THE PROB, WE DECIDED THAT SETTING AN OUTBOUND ALT DURING TAXIING IN IS NOT ONLY ILLEGAL BUT UNSAFE. WE ALSO DISCUSSED OUR CLRNC REFING THE ORIGINAL COPY DURING THE BRIEF.
