I am replacing the light switch in my old home (1981). I can see that all grounds are at the back bundled together. Do I still have to legally connect the ground to the light switches' ground screw?



PS: The light on the ceiling is properly connected to the ground.

          Yes. Modern code requires switches to be grounded. If you are not using self grounding switches and metal boxes (and you are not), you need to run a wire from the switch ground screw to the bundle. Attaching to the end of any one of those wire will do.



          Supplement: While the electrical police are unlikely to come pounding on your door, there is a reason for code. The ground serves as a safety if the switch gets damaged. It prevents the (rare) chance of you flicking a damaged switch and getting a shock. It's worth the trouble. In general, when you do an upgrade or a fix, you bring the device or system up to code if it is possible and reasonable. In this case it is both.

          • Does the legal requirement apply also for old construction? I've seen many houses that do not even have wiring in the walls that has a ground.

          • Will it be okay if I pull the ground from spare romex that I have and loop it around the existing bundle and then to the screw? Normally I would use the plastic screw top to merge wires together but since these are already bundled using a copper compression thingy, I wonder what would be the best way to connect the ground to the screw.

          • Wrapping is not likely to be sufficient. You need a wire nut or a push in connector or a crimp connector to be sure of a real bond. It looks as if the bundle has ends that could be flared a bit to accommodate. Check the electrical connections aisle of your hardware store for one that would fit. It does not need to be insulated.

          How many registers does an x86_64 CPU actually have?

          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
