Question

lightening arrestors


I would like to hear opinions on how to install lightening arrestors on a new house. Has anyone had any experience with this?

What is the specific problem you want to protect your house from?

Lightning directly hitting the house? Trees? (Lightning rod system.)

Or electrical surges on the power lines? (Surge protection.)

(Or both?)

lightening arrestors


My experience is with commercial lightning arrest systems used on wireless telephone towers. The basic idea is to install a grid in the ground, which typically includes several deep penetrating copper rods connected by relatively heavy copper cable, and install a lightning attractor at the top of the tower which is connected by a large diameter copped cable to the buried grid. The size of the grid, the number of rods, and the depth of burial depends on the resistance of the soil.

These are very expensive systems, likely way beyond the price point of a homeowner. The lightning arrest systems I have seen on houses look like they include a lightning attractor, a copper cable leading down to a grounding rod. I am not familiar with the performance of a home system, I do know that the commerical systems are very effective at minimizing voltage spikes to the equipment, and minimizing damage to the tower.

I would suggeset to look into SyCom's SYC 120/240 surge protection unit for the panel.
