Applications Permitting Supplementary Protectors
Supplements or provides additional protection for
sensitive electronics inside the equipment.
Used on the load side of branch circuit protection to
protect critical or sensitive internal circuitry such as:
• Computers and microprocessors
• Communications equipment
• Electronic controllers
• Power supplies
• Many other types of equipment
Permitted for protection of motor control circuits
NEC 430-72, unless transformers are in circuit,
then UL 489/CSA C22.2 No.5.
UL 489/CSA C22.2 No.5
Applications Requiring Branch Circuit Protection
Protects conductors entering the OEM equipment.
This required UL 489/CSA C22.2 No.5 device may be
provided integral to the OEM equipment or be
external as part of the distribution system.
May act as branch circuit protection
if it protects the conductor to the utilization equipment.
Required to protect convenience receptacle circuits
(internal or external)
Required to protect an external load circuit leaving
the equipment
Required for motors in the equipment
Required for HACR equipment
