Hi, Previously I guess reno electrician used a lower grade wire (snap when you pull). During this 3 years, they have to change the wire on those downlights for 4 times and this is frustrating to us. Now I wanted to change all my downlights to LED downlights, how do I ensure my electrician is using better quality wire when rewiring? Or is it better I buy the residential wire (14/2 NM-B recommended by friend in USA) from USA store for the electrician? Does Singapore use the same type of wire as in USA standard? Or anyone knows where can I get a better quality made wire in Singapore? Thanks.
