In preping house to sell was running dedicated circuit to bathroom for
gfi socket as bathroom had no socket only only light switch.
discovered that all upstairs (bathroom and 3 bedrooms) were on 2 (two)
20 amp breakers that were ganged. Also found the old wiring was 14
gage. I will of course be replacing the breakers with 15 amp
breakers. Anyone have any idea why the breakers were ganged and when
replaced must I also use ganged 15s or just one for each of the two
circuits?
