Wording on EIC

On Main switch or circuit breaker of the EIC

The differences between "current rating" and "fuse rating or setting"
I cant see a difference in the wordings used between
Current rating and Fuse rating

 

[davesparks]

Current rating is applicable to switches wheras fuse rating or setting would be applicable to circuit breakers

 

[DuaneMHunt1976]

So on a circuit breaker the current rating is circuits vales 6A to 50A and Fuse rating will be 3-5 times for a type B so 18-30a to 150-250A
Think it's getting late should try and sleep

No, the fuse rating or setting is whatever the circuit breaker is set to. Bearing in mind that where a circuit breaker is used as a main switch it's almost certainly going to be an mccb or acb

 

[Brightspark2]

As Dave says the current rating is the rating on a main switch for example in a consumer unit. It does not provide over load protection, the rating is simply the current rating of the switch. That's the value you record in the current rating on the cert.

Fuse rating or setting would be where a device is used which does have over current protection. Such as MCCB.

Current rating; The maximum current the switch will safely carry, as determined by the manufacturer and marked on it.
(above this value the switch will potentially melt, disintegrate or blow into a thousand pieces). Think of it as a piece of cable.

Fuse rating; The value of current that the manufacturer has set the Circuit breaker to trip (or fuse) at, OR if it is an adjustable Breaker, the value that it has been set to.
