Our house was built in mid 2016. The circuit breaker board looks like the foto below.
Until now I have had only problems with LED and standard light bulbs that were blown. Fortunatly no expensive electrical devices such as TVs, refrigerators, airconditioners or computers broke so far. But I am a bit unsure if it would be good to install under/overvoltage protectors or other equipment to be safe.
If somebody could give me directions, it would be highly appreciated. Also for and address of a qualified electrician in Cha Am/Hua Hin area.
