I might buy cleaner but I won't buy safer. One of the types of properties I use this in is rural residential properties with well pumps. By using an MLO panel to supply the interior panel, the well, other buildings, air conditioning, and so forth I assure that a problem in any one building will not deprive the occupants of the water to fight a fire with until their rural fire department has time to respond. I am aware that the code allows a separate disconnect for that purpose but that adds markedly to the expense of the installation.
