elcetricity question

Will it work? Yes....is it safe? Moderately. As a licensed electrician I would give you this advice. Ask the landlord to replace it and tell him that his insurance co should give him a decent cut for the upgrade. Another route would be to try and weld with it but if it blows the fuse instead of continually replacing it I would push the landlord a little harder. As an additional precaution a cheap but effective method of preventative maintenance is to get a laser temp gun and check the panel for hot spots while you have all of the loads on
