They are really to generally be free of paint or some other masking and has to be buried 10 toes deep, No matter if you employ a longer length of the ground rod, You must bury it two feet further when compared to the size of it so the highest of any length floor rod are going to be buried 2 ft beneath quality.
The severest challenges are connected with utility services traces which can be extensive systems, both pole mounted or buried, that may transmit more oblique strikes towards the setting up. A complete lightning defense technique according to the Criteria includes surge security devices at just about every entrance of developing services conductors, whether they are utility or maybe construction-mounted like an antenna system.
