I just installed a sub panel into a basement for a buddy, he

I just installed a sub panel into a basement for a buddy, he has a 200amp main, installed a 60amp to feed the sub panel, ran 6ga. New box has 100amp disconnect, two 15amp arc fault for lights, 4 20amp arc fault for outlets, plus two reg 20amp units for utility etc. anytime I put a load on any of the arc fault breakers (even one single light) the breaker will trip. wired in an outlet for the reg breakers no issue. In the main box the common and the ground are shared, when running the cable to the sub box, common is common, but the ground bar is separate with an isolated ground. Do I need to a isolated ground or what?

I have a 240v outlet with two hots and a ground, and I need to add the receptacle and hook it up to a 3 pronged cord for an electric dryer. I can only find non-grounded receptacles that match the cord for my dryer. Is the outlet going to be compatible with the dryer?

I was changing a switch in my bedroom for the ceiling light.

I was changing a switch in my bedroom for the ceiling light. In the switch box there are 3 larger heavier wires connected to each other and tied together with an orange screw nut. The wires come into the box from the top. I had not flipped the breaker before changing the switch. The hot wire for the switch touched the heavy 3 wires and blew all the outlets in the bedroom and the closet lights, but the switch still works. I thought I just blew the breaker so I went to reset it but it wasn't flipped off. Any ideas??
