Wiring and grounding are the most important steps for safety and performance. Always follow these best practices:
Use short, thick wires for all connections. Short wires lower resistance and help the device work faster.
Choose wire sizes that match the National Electrical Code (NEC) Table 250.66. Many Surge Protector Devices use 6 AWG copper wires.
Connect the ground wire directly to the electrical panel’s ground bus or neutral bar. This keeps all parts at the same voltage and stops dangerous differences.
Never use water pipes or gas lines as grounding points. These are unsafe and do not meet code.
Keep grounding wires straight and under 20 feet long. Avoid loops or sharp bends.
Apply anti-oxidant compound to all grounding connections. This stops rust and keeps the connection strong.
For homes, use a dedicated copper-clad ground rod (8-10 feet long) if needed. Install it according to NEC 250.52.
In offices or factories, bond all metal systems together and use braided copper for low resistance.
Test the ground resistance every year with a clamp-on tester. Good grounding should have less than 5 Ohms resistance.
Inspect all connections each year, especially after storms or electrical work.
⚡ Safety Alert: Always turn off the main breaker before you touch any wires. Double-check with a voltage tester.
You can now install the Surge Protector Device in your panel. Follow these steps for a safe and effective setup:
