Why This Matters

Power surges from lightning and appliances can destroy electronics throughout your home.

What You Should Do

1. Look for joule rating — 40,000+ for whole-house.

2. Check response time — Under 1 nanosecond.

3. UL 1449 certified — Safety standard.

4. Consider warranty — Many include equipment coverage.

5. Use point-of-use protectors too for sensitive electronics.
