A properly wired US home without a neutral wire to the transformer has 240V across both phases, which can leave either phase anywhere from zero to 240 VAC. Damage to 120V appliances will result unless the breakers trip first. The 'ground' connection would have to carry the whole house's current imbalance load in place of that neutral, through the earth to some nearby dwelling that DOES have a proper neutral wire, to the same pole-pig transformer, for this calamity not to occur.
