UL Power-limited Wiring Requirements
Standard Relays
The FACP provides two Form-C relays rated for 2.0 amps @ 30 VDC (resistive) and 2.0 amps @ 30 VAC
(resistive).
2.6 UL Power-limited Wiring Requirements
Power-limited and nonpower-limited circuit wiring must remain separated in the cabinet. All power-limited circuit
wiring must remain at least 0.25" (6.35 mm) away from any nonpower-limited circuit wiring. Furthermore, all
power-limited and nonpower-limited circuit wiring must enter and exit the cabinet through different knockouts and/or
conduits. A typical wiring diagram for the FACP is illustrated below.

Relay connections may be power-limited or nonpower-limited, provided that a minimum of 0.25"
is maintained between conductors of power-limited and nonpower-limited circuits.
