    Keep the connections from the supply through the SPD to the protective-earth bar short and direct. Long leads add voltage during a surge; Schneider Electric’s installation guide recommends a total connection length of no more than 50 cm where practical. Route phase, neutral and PE conductors together and follow the manufacturer’s conductor-size and backup-protection instructions. A qualified electrician should verify protective bonding, available fault current, isolation and local code requirements before energizing the board.<\/p>\n
