I would like an Electrical engineer to make connections with SWA cable that I have installed from my house CU into the CU in my garage, from the house CU the first connection would be into an adjacent isolation switch, the next connection would be into a junction box on the back of the house where the cable comes out of the ground from the garage and then a connection into the garage CU, I like to leave this kind of work to the pro's so chaps any idea of how much or there abouts, cheers
