Minorl, thanks for your comments, most of which I agree with. However, I would respectfully disagree with the following, especially in a situation such as Margot's where the power consumption of the system is not particularly high:
Regarding code compliance, Jim can speak to that more knowledgeably than I can, but it seems to me that the only way a system having typically modest power requirements such as this one could cause non-compliant allocation of loading between the two phases would be if the existing installation were already marginally non-compliant, and the electrician then chose the wrong phase (i.e., the one that is more heavily loaded) for the dedicated lines.
The bottom line: I agree with Elizabeth's initial statement regarding this issue.
Best regards,

I don't buy the argument that everything must be connected to the same tap on the service panel connection. That is really not true and it is really a violation of code.Regarding the sonic issues that are involved, see my post here, and the links provided therein (the main one being the ExactPower link, which Jim had called to our attention earlier in that thread). (Ignore the first paragraph of my post, which is on a different subject).
