Eli5: How do whole house power-surge protectors work? Is there ways that it can work better?

163 views

I was trying to research regular outlet surge protectors that go from the wall outlet then you plug your devices into it. I couldn’t grasp why those aren’t as effective as a protector for the breaker box. Is there a way to protect your whole house and can you explain why it is needed. I know absolutely nothing about electricity except you need a ground. Does ground on the breaker box differ than the protectors ground?

The breaker box IS a surge protector, that’s why breakers trip, when too much current flows through it that could damage the circuit, it trips and cuts the circuit.

But, the amount of electricity that can safely flow through a circuit is WAY higher than what can safely flow through a single device. So if you put some kind of protector/limiter on a circuit that had a low enough limit that it would be able to protect individual devices, you wouldn’t be able to turn on nearly as many lights or plug in as many devices before the whole circuit tripped.
