Aug 5 (Reuters) - More than 3.1 million homes and businesses from North Carolina to Quebec were still without power on Wednesday after Hurricane Isaias crashed up the U.S. East Coast and into Canada, according to electric companies. The remnants of Isaias, which crashed into North Carolina on Monday night, were currently located over Quebec. The storm knocked out service to more than 4.3 million customers as it marched up the coast. Most customers left in the dark in North Carolina and Virginia have already had their power restored.
