... this will prevent your house from burning down when you try running space heaters and a refrigerator on the same circuit on 80 year old wiring that should have been replaced about 79 years ago. But your landlord can't even install a shower head, let alone realize that fuse boxes are more ancient than s/he is. Ideally you'd have a circuit breaker, and a line capable of the modest load you're using on it. This, sadly, is not the case. You don't move to a nicer place because your rent is cheap (rent control and all) and you're kind of used to your landlord's quirks. So you put up with this. Then one night as soon as your bed hits the pillow you will realize you just blew a fuse. You get up, put your pants on backward and trip over your shoes, decide to forego the shoes and start looking about for a flashlight. Then you go looking for the fuses. Drat! You have no spare fuses. So you put on your shoes, right your backward pants and get in your car for a trip to Home Depot, whom you learn, does not have any such thing in stock. You'll run an extension cord from another line to power your important stuff, like your computer, and go online to order them. Thank goodness for The Internet. You buy 50 of them. Yep ...
