A reply for this from "
little dog" ended up in the wrong place. Here's his post.
one suggestion is to install a lighting contactor large enough for the calculated load including 25% for any continious loads if this is going to be used in a commercial application. Then you can feed a sub panel that feeds all the lighting circuits.All circuits would be wired to the required size breaker. When you energize the contactor the contacts would pull in and energize the subpanel and any loads being fed from this sub panel. You could just wirenut future switch legs together then at later date if necessary you could install switches. For now you could put blank covers over boxes where future switches are to be installed. At later date you could remove contactor and wire directly to the sub panel. You probably need to check with inspector to make sure this would be acceptable.
