You'll love these. The switch is wired with doorbell wire #18, to the light. There is also wiring with telephone wire 24/4 to other 120v applications.
The service cable shown in the panel is welding cable. Note the separation of the conductors. The service feeders at the inside panel is not the same as the welding cable outside at the service main. There are no apparent j-boxes. It appears the conductors are spliced somewhere in one of the walls. No grounding conductor is present either. A young lady just bought this home unaware of the electrical hazards that exist. The service was updated a few years ago.
