You're using circuit-breakers as a transfer switch, is that legal? I was under the impression that a transfer switch had to be a manual change-over switch that broke the incoming mains hot and neutral conductors.

Pool8 have you checked the BC Safety Authority web site.here on Vancouver island the safety authority put on a tech talk about back up power systems and there is a directive on this subject,you should be able to download a copy of it
The Breakers are side by side, with an interlock clip.
The TS that I am speaking of doesn't have an extra pole on the breakers for the neutrals. I was wondering about that too.
I just read that if Generator's neutral is bonded to it's own ground, then the neutrals need to be switched, but if it isn't then neutrals tie together. (I'm not entirely sure, but that's what I read).
Pool, That is correct, you do not have to break the neutral, just be sure it is isolated from ground in the transfer switch. Now go and get yourself a real transfer switch, before somebody takes the interlock off your breakers and does some damage, or worse. You can get a Cutler Hammer 200 amp switch from Harbor Freight tools for around 200 here, i think its worth that much for peace of mind, not to mention liability.
