How wattage/amp ratings work when plugging things into power strip/surge protector?

I just don’t get it. Only a handful of devices would put you over the 15A limit right?

They are all added together so the sum of the power draw is limited to what it can handle which often is 15A.

It is technically not the rating that is listed on the device, that the max power it can draw but what is really draws when they are used that matters. But to be safe assume the use max power is a good idea.

15 A will result in 15 * 120= 1800W or 15* 230 = 3450 W depending on where you live.

That is quite a lot of power and stuff that is typically used in a household it will be objected that are designed to heat up stuff that uses lots of power. An electric kettle, electric oven, stove top, portable AC, space heater etc, I would suggest connecting them directly to a wall outlet or realy check so you might not draw to much with all of them on,

Most other stuff we use does not draw a lot of power. Even large 60-inch TV with LED illumination is sub 100, double that for an older LCD illumination system. A powerful gaming PC might be at 350W. Gaming computer is sub 100W and the phone charger are sub 20w. LED lamps are typically less then 10

So most of the time when you want to put in lot of devices that will not draw that much so the limit is not relevant.

Unless what you plug in produces a lot of heat it will not use a lot of power and filling up a power strip works fine.
