This will be stamped or printed on a plate on each piece of equipment, you don't need the manuals for that. The numbers given are conservative, so if you can meet them you should be just fine. Add up all the things that will be on at once, and make sure you can meet that load. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
