Hi everyone. I'm getting ready to have a new central acsystem installed and I decided to save some money and pull the wiring to my panel myself. I need two 220v 30amp lines pulled. One to the outside carrier condenser and another pulled to the attic for the air handler. I also need a 115v 20amp line pulled to a seperate split mini system down the length of the hide. I plan going from the panel in my basement through the wall to the outside where the AC unit is as well as up the side of the house to the attic. The 115v line will also come out of the house in the same area and travelling Dow the length of the house 50 feet in conduit. My question is can I put all 3 wire pulls together in conduit through the wall and then pull each line seperately to their location or do I have to have 3 holes in the house to keep the wires separated? If I can have them together what parts do need? LB fitting? Junction box? What size PVC conduit? Help would be very much appreciated

#6wire from panel to airhandler with 60 amp breaker if running 15 kw heat strips,# 10/3 wire from panel with 30 amp breaker at panel running to a/c condensor with pullout non fuse box, or 30 amp breaker box also you will need a/c whip from there to your unit, as for other wire your running it depends on what amps are required for the system, 20 amps requires #12 wire
