Can i use the same earth rod for both earthing and lightning arrester
Hi guys. Still, on electrical tutorials, we’ll be taking a look at if it’s advisable to use the same both earthing your home and for lightning arrester.
In previous articles, we’ve talked about the meaning of earthing and that of lightning arrestors. We’ve also looked at the various ways you can earth your house and install lightning arresters in your house. Also, we threw some light on the difference between earthing and lightening arresters and why they are both necessary in a house. Lastly, we took a look at why we need charcoal and industrial salt while inserting earth rods to the ground.
Why you can’t use the same earth rod for both earthing and lightning arresters
From the heading, I’ve answered the question above. Yes, you can use the same earth rod for both earthing and lightning arrestor but it is disastrous. So, don’t ever try using the same earth rod for both earthing and lightning arrester. The next question would be “why can’t I use similar for both and lightning arrester?” It’s pretty simple.
It technically has no effect till there’s a lightning strike. The voltage associated with the lightning will cause current to flow from the lightning arrester to the general earth of the mass via the copper tape and copper rod. Remember you’ve connected the earthing of the house to the same rod. Due to the high voltage, some current will escape and flow to all the earth links in the house which will technically destroy some of the electrical equipment if not all in the house.
For this reason, it’s advisable to use different earth rode for earthing and lightning arresters in your house.
