Conductor Sizing for SPD Connections

Follow manufacturer minimum cross-sections.

Datasheets specify minimum Cu cross-sections for L/N/PE connections. Undersized leads overheat under surge or fault.

Use proper ferrules, torque, and strain relief. Loose SPD PE is a silent failure mode.

Label SPD circuits clearly so future electricians do not "tidy up" by lengthening leads.
