Can i use the same earth rod for both earthing and lightning arrester: I have already addressed the question in the headline. The same earth rod can be used for both earthing and a lightning arrestor, although doing so is hazardous. Therefore, never attempt to ground and act as a lightning arrester using the same earth rod. The following query is, “Why can’t I use a similar earth rod for both earthing and lightning arrester?” It’s fairly easy.
Technically, it is ineffective until a lightning strike. The copper tape and copper rod will allow current to pass from the lightning arrester to the general ground of the mass due to the voltage connected with the lightning. Keep in mind that you connected the house’s earthing to the same rod. The high voltage will cause some current to escape and flow to all of the earth links in the house, theoretically destroying some, if not all, of the electrical equipment in the house.
Use various earth rods for earthing and lightning arresters in your home for this reason.
