These wires are from our club roof which is connected to the solar panels and goes down to the ground level to the electrical switch room.
I was told these are DC then converted back to AC in the switch room.
I don't know which DC or AC is more danger
Shouldn't these wires have protection cover over them?
This is on our roof, shouldn't the cable trays be slotted together supporting the joints?
As you can see, they used screw/plug into a paving slab and it's sliding down the roof
