Is is a famous brand ? or any cheap brand is enough ?
Buy the way, I checked in the condo row fake rood, and only 2 cables, the black and the green go into the room, does it mean that the ground is not connected ? Should the ground be coming from the meter box as the green and black wires are coming ?
Or can a earth wire be connected directly to the ground from inside the condo (1st floor condo with only car park under).
thank you so much.
