Hi there. I am a DIYer and am located in Ontario, Canada.
I would like to put in a dedicated 20 amp circuit into my attached garage for my 15 amp table saw. The circuit will only have one tool on it at a time (the lights and existing outlets are on their own 15 amp circuits and will be left in place). I know it would be best to install a sub-panel for future expansion, but I really only need the one circuit. My question is about the length.
It is 60 feet to the attached garage wall, and then another 20 feet to install the drop-down outlet on the ceiling. Normally I would use 12/2 wire, but due to the length, it will be over the 3% voltage drop guideline. Is this too far over the length guidelines to make this work? I will never be pulling the full 20 amps. The saw has a 15 amp motor, but I am sure it will spike on start up and under heavy loads. The saw will not be used on a continuous basis, and will usually be run for only a few minutes at a time. I will need to check the code here in Ontario to see if I need AFCI protection in an attached garage or just GFCI.
Would it be better to run 10/2 wire the 60 feet to the attached garage wall and then splice to 12/2 wire in a junction box to go the extra 20 feet or so to the drop down outlet, or can I get away with the 12/2 the whole distance for this application?
Thank you for any suggestions you may have for this application.
