    I WANT TO INSTALL A SPD ON MY HOUSE BUT I AM GETTING CONFLICTING ADVICE.
    HOUSE IS IN THAILAND WITH LOTS OF ELECTRICAL ACTIVITY. I HAVE A 50 KVA TRANSFORMER ON SITE SUPPLYING 3 PHASE POWER TO THE HOUSE. THE TRANSFORMER AND METER IS LOCATED ON A POLE ABOUT 60M FROM THE MAIN SWITCH BOARD IN THE HOUSE.
    LOCATION – SOME PEOPLE TELL ME TO LOCATE SPD ON THE POLE AND SOME SAY IN THE SWITCH BOARD. WHO IS CORRECT?
    SPD SIZE – SOME PEOPLE TELL ME TO GET A 4 POLE 20 KA DEVICE BUT OTHERS SAY 3 POLE 40 KA? I HAVE SEEN 3 POLE, 3 POLE + N & 4 POLE. ALL COME 10, 20, 40, 60 & 100KA. WHICH IS THE CORRECT DEVICE FOR MY SITUATION
    I HAVE LOOKED ON THE WEBSITE BUT CAN’T SEE ANYTHING RE SPD FOR 3 PHASE CONDITIONS. CAN YOU PROVIDE SOME ADVICE RE THE ABOVE.

    Hello, guys. Thanks for you such nice post to teach us more details in this field. Usually we will use the surge protector to protect our equipment from charging. Especially for light. So we are used to choose a good quality surge protector to charge tools. The tool for me is bestek 4 outlet surge protector, friend recommends this tool to me two years ago. There is no damage of any tool. Maybe you can search bestekmall on Google to learn more details about it. Hope this point is useful to you.
