Rating:
2 A, maximum
Wiring gage: 18 AWG (min.)
to 12 AWG (max.)
Wiring Notes:
1. All wiring from the AUX/NAC is power limited.
2. Conductors must test free of all grounds and stray voltages before connection to appliances and panel.
3. Terminate Class B NACs as shown using 733- 894. For Canadian applications, mount end-of-line resistor to Simplex-US Model 431537
EOL plate in accordance with ULC-S527.
4. If circuit is terminated with a 10k EOLR, at the terminals, remove this resistor before wiring.
5. If wiring is routed outside the building, use of a listed secondary protector is required. Use Simplex 2081- 9028 or 2081-9044. A
protector must be installed at each building exit/entrance. Each 2081-9028 adds 0.2 ohms wiring resistance. 2081-9044 adds 6 ohms
wiring resistance, and will greatly reduce wiring distance.

Note:
This Chart indicates the maximum distance for 1/4 -2A loads. Wiring distance is from the panel terminals to the last appliance. Use of a
2081-9044 protector reduces wiring distance.
