Hi, I have two 4-way switch questions please. 1. I have a working 4-way circuit. I'd like to out an intermatic astro timer on it. It works with single and double pole. No one seems to be able to confirm that this should work if I install at a 3 way switch and jumper the oth 3 way switch. Maybe because it is electronic there may be snags? 2. I have a non working 4-way circuit. The lights work but it in all cases. Is there a way to test this by writing down all the permutations to figure out which of the 3 switches need checking/fixing/changing? Thanks

on one wall of my condo, the outlets are wired such that the top plug is on one 15amp circuit and the bottom plug is on another 15amp circuit. the bottom plug is switched (eg, expected that lights would be plugged into the bottom outlet) - and the top is always live (no switch). i was rewiring some of this such that the plugs are on a SINGLE circuit (and the bottom/switched circuit is out of the equation - so id basically disconnect and cap off the hot wire for the bottom plug). in doing this, i discovered that there appears to be a SINGLE neutral wire servicing both plugs on the outlet - and then separate HOT wires for each circuit for the top and bottom plug in the outlet. is there supposed to be a separate neutral for each circuit when sharing an outlet like this?? or can they share neutral? what happens when im using 10amps from EACH circuit in the outlet?
