Hamilton Lightning Rod Systems

HLS Installation

We Can Retrofit To Your Existing Home Or Conceal All Wires During New Construction

Lightning protection systems (Lightning Rods) are designed to help prevent damage and potential fires that lightning may cause. This is done by reducing the flow of electrical energy (lightning) traveling through flammable building materials in structures.
A standard Lightning Protection System is comprised of Strike Termination Devices (air terminals or the rods) along the ridges, flat-roof portions and perimeters.
These lightning rods are interconnected with specialized lightning protection conductor cable coursed throughout the building and terminating at grounding locations, a grounding cable to carry the positive charge to the ground through a grounding or termination rod.
Optionally it is also recommended to install a surge suppressor to isolate the expensive home electronics from an electrical surge caused by the lightning strike. The surge can occur even if the lightning does not strike your house.

Basic Lightning Rod Installation

All Materials NFPA 780 and LPI 175/177 Requirements
  •   1) Copper grounding rods installed 10’ feet deep, or solid copper plates depending on soil (rocky ground).
  •   2) Parallel cable connector (splicer)
  •   3) Air Terminals (Lightning Rods) spaced 20 feet apart along the ridges - dormers - peaks etc, and within two feet of ridge ends.
  •   4) Air Terminals (Lightning Rods) located on chimney.
  •   5) Cable fasteners placed approximately every 3’ feet to keep the system neat and tightly secured.
  •   6) Pipe connectors used on water - gas - and any metal conduits entering home.
  •   7) Whole House Surge Protection Device installed on the main electrical panel box (breaker box).

Material We Use On Residential Homes

Conductor Cables

Copper conductors: 1/2″ diameter braided cable consisting of 32 strands of 17 gauge copper wire.

Aluminum conductors: 5/8″ diameter braided cable consisting of 26 strands of 14 gauge aluminum wire.

Air Terminal Rods

Copper sizes range from 3/8″ x 10″ to 1/2″ x 24″

Aluminum sizes range from 1/2″ x 10″ to 5/8″ x 24″

Rods over 24″ are available to order with a required brace.

Ground Terminals

Copper ground rods ranging from 1/2″ x 8′ to 3/4″ x 10′

Lightning Arrestors

These devices are installed on electric service panels to prevent dangerous high voltage from entering a structure through the incoming wires. The arrestor works as a filter to defray incoming voltage, thus preventing a lightning-induced electrical fire or explosion.

Surge Suppressors

These are installed between the appliance, electronic equipment or computer and the electrical outlet to provide point-of-entry surge suppression from lightning induced power surges. Structures which contain sensitive electronic equipment may require a series of individual surge suppressors. Surge suppressors are not a required component of UL approved lightning protection system and can be implemented with the lightning protection system at the owner’s discretion or per installer’s recommendations.

Ornamental Points

Ornate points are available in a variety of selections to enhance the appearance of traditional lightning rods of a structure.

Commitment to Excellence from Hamilton Lightning Systems

We will conceal the cables as much as possible by utilizing the roof ridge lines keeping all cables fastened down to the back side or the most inconspicuous side of the roof ridge line.
There should be no visible or very minimal cables showing. The same goes for the down-leads going into the (grounding rods are buried in the ground) on the side of the house. We will use the gutter down spouts and fasten the cables to the back side so same as the roof there should be no visible cables looking at the house from the front street view, cables are aluminum in color 5/8 in diameter braided wire, lightning rods are aluminum in color 12" in height and 1/2" in diameter, grounding rods are 10' feet, 3/4" inch in diameter and buried in the ground so the rod or ground clamp is not visible also a person can't trip on it or get damaged by any lawn work or equipment.
