Not one bulb, but two in series (because one will burn out immediately); the normal way is to use six bulbs, two between corresponding fases of the two generators; when all bulbs are out, you can put the second generator on the distribution bars, because that way they are phase synchronized. Have done myself this way with two hydro-powered 50 kVA generators somewhere in Northern Argentina, in a small Andes-town... Albert Smulders InSAD - Encarnaci—n, Paraguay insad@itacom.com.py
