Installing a Lightning Conductor

[@gregcarroll9723]

Great way to ensure protection of sensitive electronic equipment. Thermal welding is certainly different. Leads me to wonder if brazing is used in Thailand.

[@MatPoyobro]

Is it sufficient only one conductor installed on top of big roof.how if lightning strike at the other side.not the side with the conductor?

[@AmericanInThailand]

I had no idea about any of this. That was very interesting! Thanks!

[@electrowashyelect9715]

If a standing tower is behind the installation. Cant that the lighting arrestor if the towel gives a cover for the solar installations.

[@electrowashyelect9715]

The arrestor cable is sheilded from the building how about the solar panel frame is it necessary to be earthed ?

[@chargeheadsuk]

Where is Thailand is this?

[@awaisahmed4322]

What is the size of a down conductor?

[@firstname5556]

Do you also have a separate electrode linked to the Earth bar in the distribution board?

[@EcoHouseThailand]

I have a separate ground rod for home electrics, another for my solar system and another for my solar thermal immersion heater.

[@firstname5556]

@@EcoHouseThailand Did you also test the soil resistivity and external earth fault loop impedance?

[@TheStev08]

did they bond the Lightning System to the Solar Grounding system? or it should be seperated?

[@EcoHouseThailand]

The grounding for the lightning conductor is separate from the solar grounding and much more substantial

[@TheStev08]

@@EcoHouseThailand Thanks. It is good to know that it should be seperated. Is the AC and DC ground of the system is seperated also?

[@EcoHouseThailand]

@@TheStev08 Yes

[@keegang7402]

According to the NFPA780 the grounding systems should be bonded

[@SgtJoeSmith]

@@keegang7402 yeah i thought you bond anything metal, railing, pipes, solar panels, ac units on roof, lights, antenas, etc
