Plug Nightlight LED lamp is two to the three-phase good or good?
Guess you want to ask three claws of good or two claws of good, in fact, all the same, just to adapt to different sockets.
The two plug is a zero line, a line of fire, so the two plugs, the three plugs are more than one ground, PE, from the security point of view, three head good!
Three plug in, because it comes with a grounding wire, will not leak.
The upper claw in the three jaw is protected by the earth wire. The purpose is that once the casing is electrified, the ground guard will not be electrocuted by touching the case. But the night light is not ground plastic shell protection, so say no.
