Greetings,

If the wire is 12-2 should it be stapled to the 1x or should it be stapled
to the rafter directly beside the 1x (I assume the rafter--but I don't want
to assume incorrectly)? Is a 1x3 (*nominal) sufficient?

Thank you very much for your help,
William

What is the proper way to protect the NM wires running perpendicular to
the
rafters if I cannot drill holes

You run 1x boards next to them, the wire sits in the "valley".
