    Thats another way to do it. Plug a 10ft grounding rod in your lawn, run a gauge 6 wire (the bigger the better) near the UPS outlet, connect to copper ground bus bar(this will serve as distribution point), run a wire from busbar going to outlet, replace the outlet with 3-prong, connect your 3-prong UPS.

    If it is impossible to plant a grounding rod, connecting to any metal rod like G.I pipe of your house plumbing is a hit or miss thing. Sometimes it could do more damage but most of the time it works. Take for example the refrigerator or any motorized appliance, they produce leak current that electrocutes anyone who touches the ref metal handgrip.. Running similar grounding mod could help eliminate those leaky current.

    Usually building and industrial applications has this centralized ground point. The rods are planted forming a matrix.
    In data and telecommunication setup, aside from lightning protection, grounding acts as a shield for low frequency electromagnetic interference. For powerplant, this is much required-even small generators nowdays have earth provision.

    LCD TV? IDK if may Samsung shop pa dyan sa may Quirricada, last time sa Sta Ana ko binili yung power supply ng TV ko. Sa may Reina regente sir CB may pagawaan doon after ng BDO, tapat ng SBTC.

    Switching power supply na ngayon ang mga appliances, usually swap lang ginagawa sa quiapo ng mga technicians bihira yung nag rerepair ng pyesa mabusisi kasi.

    Lightning always strike the highest conductive surface it could reach, thats why transmission lines, cable lines & external antennas are susceptible to this natural phenomenon

    When you experience thunderstorm in your vicinity its advisable to switch off the TV & disconnect the antenna cable to the TV

    your CATV installation should have a surge protector installed by the CATV provider... but if you say from CATV ang souce, dapat pati equipment nila nasira... properly earth grounded naman ang CATV providers, wag lang ninakaw ng mga squatters yong earth ground cable...
