just contemplating the hassle I have at the moment running power to the detached garage on the few occasions when I need it.
I have to run an extension lead out through the patio door (which will then not quite close) and across the lawn/path to the garage.
Having just run some co-ax through the wall as part of a satellite installation, I thought "Why can't I do that with an extension lead - take the plug off, run the cable through the wall, put the plug back on and then run the lead into the garage?"
I could then refit the plug, and plug the lead into a socket and switch on whenever I needed power.
Granted that I would have to do a similar thing at the other end to be able to shut the garage door.
Is this a valid thing to do as it will be a lead with a plug at one end and a socket at the other just like a normal extension lead, just run through a couple of walls?
