This is for a Canadian Oven being installed in Canada.
Used oven came with this box.
The manual is not available.
The incoming line from both oven and junction are Red/White/Black/Ground.
I understand that the 120V needs the neutral to balance it for the clock/timer but am unsure how.
Control board.
To the left of the white connector it reads 120V
Light switch.
asr 2178-179
203863-1020
10A1/2HP 120VAC
Broil/Bake selector.
Tempature dial.
Interior back.
I am not against using a volt meter but not sure what I would be testing with it.

The fuse box appears to be superfluous -- standard 4-wire 120/240VAC ovens do not need this sort of rigging. It appears that some antiquated built-in ovens brought their control circuit hot out separately from the oven element hots, hence the fuse box.
