I was thinking that it must be: 1 A certain size ground wire according to lightning protection rules? Any guidance would be appreciated Location Florida. I believe only a 6 would be required by the NFPA for this application. Location North Carolina. Re: weathervane grounding The lightning protection system ground terminals shall be bonded to the building or structure grounding electrode system. This section requires that the electrodes for the Air Terminals is to be bonded to the building ground electrode system.
Location Westchester County, New York. Re: weathervane grounding Shortcircuit2 From NFPA 4. These slender structures shall require one strike termination device, down conductor, and ground terminal. Electrically continuous metal structures shall require only bonding to ground terminals. For some more guidance: 3. Down conductors shall be as widely separated as practicable.
The best thing to do is plan ahead. Look at our suggested Mounting Diagrams. Print out the pages and give them to your builder or the person who will be installing the vane, before the framing stage of construction. If you need further help call us at Do you have any mounting brackets for the copper weathervanes? The commercially available ones tend to break and are difficult to fit to your roof.
It is very strong and easy to mount on any pitch roof. It is made of quality steel, so it will need to be repainted every several years. We do not offer the Scroll Bracket alone - we only offer it with the purchase of a weather vane. How do I tell the wind direction from a weathervane? A properly designed and balanced weathervane will traditionally point into the wind, thereby showing the direction that the wind is coming from.
Unless of course, it is designed otherwise as in our Dragon design that was designed to face his back to the wind. But then a Dragon can do whatever he wants, can't he? Can I design my own copper weather vane? Check out our What is a Weather Vane page for the basic rules and things to think about when designing a weather vane.
Then go to our Custom Weathervane pages and our Custom Silhouette pages for more ideas. I have an idea for a weather vane, but I don't see it already on your website and I'm not an artist.
What can I do? We have designed many weathervanes from photographs, magazine clippings and simple doodles or sketches provided by our customers. How do I figure out what size weather vane or finial will suit my building? There is no reliable "rule of thumb" that will work for all applications. If you send us a photo or scale drawing along with a description of the setting and all dimensions of the subject building, we will use our years of experience to help you with the proper sizing.
Hint: it's easy to be fooled into thinking too small I need the weather vane fast because the roof needs finishing. You have a lengthy production schedule. Then we will be happy to make and send you the mounting rod for the weather vane ahead of time usually within 2 weeks. This should enable you or your contractor to finish up and waterproof the roof.
Isolated houses and houses in elevated, exposed areas run a greater risk of lightning strikes, but tall structures and tall terrain features nearby could give a home good passive protection. Why are you safe from lightning in a car? In strong electric fields, rubber tires actually become more conductive than insulating. You're safe in a car because the lightning will travel around the surface of the vehicle and then go to ground. This occurs because the vehicle acts like a Faraday cage.
How much does a lightning rod cost? There are aluminum rods and copper rods. Cooper rods are more expensive than aluminum rods. The number of rods used will depend on the size of the roof. What is the best material for lightning protector?
The main attribute common to all lightning rods is that they are all made of conductive materials, such as copper and aluminum. Copper and its alloys are the most common materials used in lightning protection. Are houses grounded for lightning? What happens if lightning hits a house? Power Surges: When lightning strikes a house, the electricity often surges through a home's wiring or plumbing system, searching for the quickest possible route to the ground.
The most common place for a fire to ignite is in the attic, when a lighting bolt comes through the roof or top of the house. What are the odds of lightning striking your house?
