A manufacturer's built-in surge claim should be checked against the actual project requirement rather than treated as a substitute for a coordinated design.<\/p>\n

Document the nominal supply voltage, earthing arrangement, available fault current and the cabinet's existing protective devices. Check whether the installation calls for a Type 1, Type 2 or coordinated arrangement based on lightning exposure and the project's applicable rules. Select the AC SPD's continuous operating voltage (Uc), voltage protection level (Up), discharge ratings, short-circuit rating and backup protection from its datasheet.<\/p>\n

Do not copy an SPD fuse rating from another model. The existing upstream device may already satisfy the manufacturer's conditions, or a dedicated backup device may be needed.

A pole-mounted SPD may offer a serviceable protection point closer to the luminaire, especially where the feeder-to-luminaire cable is long. It must fit the pole's electrical compartment and environmental conditions. Verify the enclosure rating, terminal capacity, conductor routing, earthing and bonding, and how a technician will identify a failed cartridge during maintenance.<\/p>\n

Keep the SPD leads short and direct according to the manufacturer's instructions. A long, looped connection can increase the voltage that reaches the LED driver during a fast transient. Never assume that a green status window proves the whole pole installation is correctly protected; it usually reports only the monitored state of the device.
