My real question is about the split receptacle. Does the neutral tab need to broken or just the hot? It's on a tied breaker with two hots but only one neutral. I think the tab should connected since they share a neutral (read Electrical Code Simplified and online) but the tab on the existing one is broken.
Thanks to all who have provided help over the years- Drew, divx, MrSparky, retrovette and anyone I missed.
