Double Sided LED Sign Installation on Wall

1) Project Summary

Install a double-sided corner-mounted LED sign upgrade, with two 3' × 23' single-sided LED displays arranged in a V-shape meeting at the corner of the building, alongside two non-illuminated static signs. The new signs replace the existing outdated corner displays while maintaining the same position for maximum visibility from the freeway in both directions.

6) Wiring Specifications: How to Connect the Sign

Electrical Recommendations

4 circuits of 20 amps per side, for a total of 8 circuits for the double-sided sign. Circuits must not be shared and must not be on a timer.
An indoor disconnect switch is recommended to allow power to be safely cut in the event of an emergency or extreme weather.
The power connection point should be within 5 feet of the sign to accommodate the sign's onboard cables. Running power to that point — whether from a breaker panel, conduit, or junction box — is outside the scope of installation and should be handled by a licensed electrician.
