When it fails. You have no way of knowing "IF" something is about to happen to the breaker. If it fails in the open position it i snot a danger, but an inconvenience because it must be replaced. If it fails because it doesn't trip under an over-current situation it could cause damage in the panel, wiring or potentially cause a fire. Unfortunately there is no way to predict this and take preventative action.

A Breaker Box is that framework which contains devices known as fuses, circuit breakers, etc., where a main line is broken down into sub-circuits. The box itself must conform to codes and standards in effect at the time. For instance, in the mid-20th century, round circular fuses were used in lieu of today's more common circuit breaker. The latching devices for circular fuse holders, in order to install such within the farmework of a breaker box, did not conform to newer standards and therefore when an upgrade was considred, a new design was required.
As with any design, codes and standards exist. In this case, it includes both building codes, installation and electrical standards. Such includes minimimum distance, material, etc.
Bottom line: whenever debating an upgrade / rehabilitation, contact your local govt. building inspector and use the services of a qualified electrician to do the work. It's there job to assure a safe / functioning installation.
Failure to adhere to this sound advice can result in a voided home insurance pay-out should faulty installation / "not-to-code" installation result in a mishap. Likewise, manufacturer warranties are void if not done to code.
Sort of like life insurance, it doesn't pay out on a suicide. Be smart, use certified workers that can provide a warranty for their workmanship following installation!
Bottomline: if you are not modifying your wiring / breakers, than a box should last a lifetime. If you are modifying, ensure a certified electrician guides you. they know the codes & standards.

How is a fuse box different than a breaker box?
Both fuse box and breaker box is where power flows through either the breaker or fuse.These devises are in place to trip or burn out due to short circuits.Without them the current would continue to flow and likely cause a fire or major damage to both the wiring and devise they supply power to. The only difference is a breaker can be reset where a fuse must be replaced if they detect a short circuit.
