The main panel has a rating that determines the total amount of current that can flow out to the circuits at one time before the main circuit breaker shuts the entire system down.Most moderately sized older houses have 100 amp service, though a smaller house might only have 60 amp service.So what else do you need to know about electric systems?While it’s best to leave the big questions to electricians, these are some basics that you should know.When this happens, the fuse needs to be taken out and replaced.Since the 1960s circuit breakers have been used instead of fuses.
Older houses might only have two prong outlets, meaning there’s no grounding protection in the circuits.
It’s possible to upgrade the main panel to handle more amps.
Again, an electrician can give a buyer an idea of how much work this will be in a particular house.
If the right fuse or circuit breaker isn’t used, it can cause a dangerous situation.
Clearly, if a fuse or circuit breaker becomes problematic, an electrician should be called in to look at it.
