How many lights off one switch?
ten lights per curcuitCircuit loadingIn Canada there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.

How many outlets can you have on a gfi breaker?
Depends on the breaker. If the load at the outlets is unknown then the standard rules of 80% apply. You can only load a circuit 80% of it's maximum value. For instance, if you're connecting your GFCI outlets to a 15 amp breaker you can only have a maximum of 12 outlets. If it's a 20 Amp breaker then you're allowed up to 16 outlets and so on. In the US, you are limited to 13 receptacles on a 20 amp circuit and 10 receptacles on a 15 amp circuit in commercial or industrial installations. Any or all of these can be gfci-protected. You can install one gfci, the first one from the panel, and protect any or all the others from that one.
What is a 20 amp breaker?
For residential occupancy there is no code for the number of outlets. It depends on the load that is going to be applied to these outlets. In an average bedroom I would limit the outlets to no more than 12 unless it is going to be used as an office. In that case limit it to 10. If the lights are on the same circuit then limit it to a combination of 12 counting the lights and outlets. For a residential occupancy, there is no Code limit or load per receptacle. The number of required branch circuits is determined by calculations stated in article 220 of the nation electrical code and are related to square footage. Certain branch circuits, such as kitchen, laundry, and bathroom cannot serve other areas. That said, it is good practice to limit the number of general purpose lighting and general purpose outlets per circuit. Your local inspector may choose to be more stringent than the actual Code requirements.
What is the standard screw size for an electrical socket ie to screw it to its metal box mounted in the wall?
The screw size is a 6-32. This relates to diameter size of #6 and 32 threads per inch. The length for receptacles is usually 3/4 of an inch.
