Just curious, working on a house that the range and dryer each only had 3-wire cables landing in a subpanel. The subpanel was wired with 4 conductors (as a subpanel in same building should be). Where would you have landed say the bare ground of the 10/2 NM of the dryer, on neutral or ground bus?
The existing wireing of the range and dryer landed differently, one of them on the neutral, the other on the ground. Based on the wire it could have been that way for more than 30 years.
Could have landing the wire on one vs the other caused or contributed to the breaker of the dryer becoming fused to the bus of the A side of Single-Phase? (Cant separate the breaker from the bus.) Found similar fusing on the 100 Amp main breaker of the same phase in sub panel (set screw welded). Heat damage on the 100A wire all the way back to main panel on that same phase.
Fyi, Panel is being replaced as well as feed wire back to main panel, upgrading range and dryer to 4 wire as part of a planned kitchen rewire and upgrade.
