6. Coffee Maker: Coffee makers should never be connected to any kind of power strip or extension wire because owners are unaware of how much electricity these devices consume.
7. Toaster: Although it may seem like it doesn’t take much energy to brown bread or bagels, toasters actually consume a lot of electricity when in use, therefore it’s best to connect them straight into the outlet rather than using a power strip.
8. Another Power Strip: Although many people do just that, power strips are not designed to be used in combination with one another.
However, because it can easily result in an electrical system overload, this is against the majority of safety rules.
