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.

Me too... old cloth wire, neutral, switched phase and phase up to ceiling light. cloth wire phase and neutral across the ceiling and down to wall sconce. from walls conce THHN buried in plaster to buried twist'n tape splice, continuing with 0,3mm2 zip cord (supposedly taken from a model railway) to another buried splice, continuing with cloth wire to a standard ungrounded receptacle...

One of them welding cables are going thru the proper KO, the other isn't. Other side of the coin, are you sure that that is actually welding cable?. I thought welding cable had 250+ strands of fine wire in it, that's what makes it flexible.

Prev. owner: "Hey the light worked, I used a box, what's the problem?"
I think Trumpy's right, that doesn't look like welding cable to me either...look at the close-up of the terminations, the strands look too big to be welding cable. It looks more like some really old fabric-covered NM (6-3 maybe?) with the covering removed.
Whomever did the service change should be forced to correct this!!
Stupid should be painful.

I hadn't thought of that permutation. Exactly how would cable insulation like that stand up to air-borne moisture, considering that this unit is outdoors. Oh and one other thing, Joe posted an image of the IEC "Test Finger" up in the General Discussion Area. I'd be interested to see the box and switch pass the test with the Finger. No cheating now.
