What is the maximum circuit breaker size recommended for primary wiring to an alarm system?

The recommended maximum circuit breaker size for primary wiring to an alarm system is 20 Amps. This limit is put in place to ensure that the system has adequate protection against overload conditions. A circuit breaker that is too large may not trip during an overload, which can lead to potential damage to the alarm system or even create safety hazards like electrical fires.

By setting the maximum size at 20 Amps, it balances the need for sufficient power supply with the safety requirements for the components used within alarm systems, ensuring components such as receivers, sensors, and control panels receive appropriate protection from current surges. Many alarm systems are designed with specific power requirements that fall within this range, making 20 Amps a suitable threshold for operational integrity and safety.
