2. USE A CONTINUOUS CABLE FROM THE POWER CONVERTER
TO THE FLASHHEAD WITHOUT JUNCTIONS OR SPLICES.
7. OTHERS TYPICALLY FURNISH THE JUNCTION BOX FOR DISTRIBUTION WIRING
TO THE MARKERS. LOCATE THE JUNCTION BOX AS CLOSE AS POSSIBLE TO
TO THE POWER CONVERTER.
8. FTCA RECOMMENDS USING #12 AWG AS THE MAXIMUM CONDUCTOR SIZE
FROM TB5 TO THE JUNCTION BOX. USE LARGER CONDUCTORS FOR THE
BRANCH FROM THE JUNCTION BOX TO THE MARKER FIXTURES, IF REQUIRED.
SEE NOTE 9 TO DETERMINE THE BRANCH CONDUCTOR SIZE.
9. THE TOTAL LINE DROP, INCLUDING THE INPUT SERVICE WIRING
AND BRANCH LINES TO THE L-810 MARKER LIGHT SOCKETS, MUST
NOT EXCEED 3% OF THE RATED VOLTAGE.
