In your typical household panel there is no isolation. If you're lucky there's a GFCI for the bathroom and kitchen.
Edit: not to imply GFCI provides isolation either
Wait so, if your kettle fails, your fridge loses power for example?
In Murica, the kettle tripping a circuit breaker would knock out the fridge if the fridge was on that breaker circuit. Anything not on that circuit breaker is fine.
No isolation here just means that if the breaker doesn’t trip, the kettle’s circuit and fridge’s circuit are connected together in the circuit breaker box by copper bars.
Ah yep that makes sense though I'm following now
