Sub Panel - Sizing Questions
I am putting in a sub panel in a new section of my basement to run some power tools. My questions are :
1. What size breaker do I need in the main panel. The panel is full but because I am moving my saw I can take out a double 30 amp breaker and replace it with what I need. The largest load at a single time would consist of table saw and cyclone. The table saw is rated at 18 amps and the manufacture says you should use a 30 amp breaker. The cyclone has max amp draw of 14 amps. Both are 220 volts.
2. What size wire to feed sub panel. Can I use copper. The distance is between 35 and 40 feet from the panels.
3. In the new basement I want to run one 220 romax cable for 3 separate tools and just branch off that run a very short secondary run for the box with the receptacles. Thus there would be two boxes where a tool was. One for the splice and a second for the receptacle. Is that a problem? Only one machine would ever run at a time and the cable would exceed the needs of the saw which use the most power.
