Lightning Ground Rod Installation in SW Wisconsin
A ground rod is the last line of defense in any electrical or lightning protection system — it's the path that takes lightning current safely into the earth and away from your wiring, your appliances, and your family. If your home, barn, or business doesn't have a properly installed and bonded ground rod system, every storm is a roll of the dice.
Lightning Ground Rod Installation
The National Electrical Code requires every service to be grounded with at least one approved grounding electrode — typically an 8-foot copper-clad steel rod driven into the earth. For lightning protection systems, NFPA 780 calls for additional ground rods at each down conductor, bonded together to create a single-point ground (SPG).
Sparks Electrical Solutions installs lightning ground rods for new construction, retrofits, post-strike replacements, and insurance inspection corrections. We drive copper-clad rods to full NEC depth, bond them to your service panel and any LPS down conductors, and test the resistance with a clamp-on ground tester to confirm the system meets code.

Frequently Asked Questions
How deep does a ground rod need to be driven?
Per NEC 250.53, the entire 8-foot length must be in contact with soil. If solid rock is encountered, the rod may be installed at not more than a 45° angle from vertical or buried in a trench at least 30 inches deep.
How many ground rods do I need?
NEC requires a second ground rod (typically 6 feet apart from the first) unless the single rod measures less than 25 ohms of resistance. NFPA 780 LPS systems usually require one ground rod per down conductor, all bonded together.
Can I install a ground rod myself?
We do not recommend it. Improper bonding, undersized conductors, or corroded clamps can render the entire system non-functional — and your homeowner's insurance may deny claims if the install isn't done by a licensed electrician.
How long do ground rods last?
A properly installed copper-clad rod typically lasts 30–40+ years. We recommend visual inspection every 5 years and a resistance test if your area has had a major strike.
Do I need a permit?
Yes — ground rod installation as part of a service upgrade or new circuit requires a municipal permit. We pull it for you.
