By blocking I guess you mean a wall supporting the joists.

Old school way is half the span plus 2, so if the span is 12 feet then half is 6 so add 2 to the 6 and you get 8, so the timber needs to be 8 inches deep.

How to run wire through joist?

Drill a hole large enough and pull the cable through. The hole must be 1-1/2" from the edge of the joist to prevent nails or drywall screws from penetrating the cable. If the hole is less than this distance, a nail plate must be installed over the edge of the joist so when the wall covering is added, a screw or nail can't penetrate the wire. Any hole drilled through a joist must be no more than a fifth of the depth of the joist and should be as near as possible to the centre of the joist. Holes bigger than 30mm are not recommended without specifically designed additional strengthening to the joist.
