This is my first time here, and I've read dozens of posts looking in vain for an answer, so now I'll ask. We are getting a new garage door with an opener installed in our 1963 home. There is an outlet on a beam right where it needs to be for the door opener, but it's switched. The installer says it needs to be hot. The switch evidently controls two outlets about 6 feet apart. The one in question has always been empty (nothing plugged into it) and the other has one of those 48" fluorescent shop fixtures plugged into it (we don't really need that light). The switch is in a double box - the other switch controls an outdoor light. Here is my question: must I remove the switch and change the outlet to an unswitched hot outlet? I have a little guard that screws onto a switchplate to prevent a switch from being thrown. Would there be any disadvantage (or danger??) in just securing that switch to an always on position? Thanks in advance to anyone who can help.

I have a 200-amp service at my house and will be working with my electrical contractor to upgrade the service at the detached garage (about 40 feet away from box) to 100 amp. (i.e. I do the leg work and he will come behind me and check my work and make the required connections) He has told me to buy 3 #2 wires and one # 6 (ground). I have dug my 18" trench and am about ready to buy materials, etc. What diameter conduit will do the job easily? I was thinking 1 1/2 or 2 would do it. Also, does the new service box to located in the garage need a 100-amp cut off if I am installing a 100-amp breaker to power the line to the garage? Thanks in advance.
