Can I plug a workbench mounted double gang outlet into a single gang wall outlet?
I like power strips similar to this for work areas. They are nice because they have an on/off switch, which if mounted in an easy to reach location could save life and limb.


Using a power strip like this should not be a problem, as long as you don't run too many tools at once.  And it should conform to most codes, as it would be classified as an extension cord (I think).
