What happens if the ballast/choke is not bonded with earth? none of the  old fluorescent lights in my house is connected the choke with earth. ( in any case I’m changing out these lights to LEd tubes next week). I also don’t see a connection point on the choke for an earth wire ( although some of the casing do have an earth wire bond which is unconnected)

My original question in post 59 was about earthing the magnetic choke ballast, not about earthing in general. ceo684 said that magnetic choke is considered a transformer so must be bonded to earth.  I suspect the last lightning strike that blew up my outdoor lamp on the choke part may have been due to this.
