I'm a layman (but not a DIYer) looking for guidance. We've been renting for over a year a modular house in the rural badlands of Arizona that was installed in 2000 in accordance with the National Electric Code per county inspectors. During this year we have had trouble with many blown light bulbs and many computer components that die sudden premature deaths. Recently the utility company came out, took a look and decided that something on the box outside was set too high at 251. They turned it down to 239, but then the main breaker would trip as soon as the electric furnace would come on. So they came back and turned it up to 244. The main breaker still trips when the furnace runs, but not immediately - it stays on for a while and doesn't trip until the panel starts to smell of electrical burn. It looks to me like an electrician is called for, but I need to be able to convince the elderly absentee landlord. Anyone out there willing to advise?

Thanks in advance for your help.
