Tronic Earth Mat 300X300

The earth mats or grounding mats are used to bring the connection to the earth indoors. They usually connect through a conductor inserted within the ground port of an electrical outlet. They help in limiting the ground potential & protect against the faulty current. What is the best earthing value? Ideally a ground should be of zero ohms resistance. There is not one standard ground resistance threshold that is recognized by all agencies. However, the NFPA and IEEE have recommended a ground resistance value of 5.0 ohms or less.
