For all typical applications, copper shall not appear into connection with aluminum or other metals wherever they should be able to corrode, specifically in a moist or wet spot. This exact same rule relates to aluminum. If applying an aluminum method, you will need to convert the aluminum conductor cable to copper cable about 12 to 16 inches above quality by making use of a Bimetal connector before you decide to connect with your floor rod(s) or plate(s).
Also, cable has to be bare. You can't have coated cable or paint your cable. If you have to paint it, utilize a non alkaline base paint and only paint frivolously.
The conductor cable which is meant to hold lightning currents through the strike stage (air terminal) safely to the ground rods and floor.
Unlike in true lifestyle, a lightning rod won't demand a immediate connection to ground in order to get the job done.
Upkeep could also be desired if cable T.V. or telephone devices have already been serviced in recent years. LPI-Accredited specialists can suggest about servicing ideas and marketplace requirements to ensure the continued functionality of your lightning safety process.

A device which will take the significant surge and voltage of electricity or lightning strike and renders it harmless by discharging it.
A device of Copper or Aluminum that is a receptor or Get in touch with level that either draws to itself a lightning demand or flash to generally be carried together the conductor route into a grounding unit.
The uncovered parts for your lightning security system are copper, aluminum, or other metal created to carry recent, present bonding connections, and keep on being purposeful within an open up weather environment. As with any other developing component produced of similar components, oxidation or corrosion of elements wouldn't be envisioned underneath usual disorders for an prolonged interval, or the traditional “life span” with the construction.
Most often, even so, properties along with other buildings should have some sort of Lightning Rod Installation or lightning security program.
Soon after First admission for the HomeAdvisor community, companies are re-screened if a concern is described to website HomeAdvisor.
A lightning safety process is meant to defend a composition from hurt as a result of lightning strikes by intercepting these types of strikes and safely and securely passing their very significant currents to ground.
Should you have questions about the challenge, question them prior to they begin. Most are pleased to operate you through the challenge and the entire process of correcting it.
UL can even inspect to Several other nationally regarded Benchmarks (like NFPA 780) for absolutely compliant methods. Some partial constructions might be available for field inspection under their “Letter of Conclusions” application.
