60a main fuse blown


I have just built an extension and now have 2 showers, obviously if I use the two showers this will blow the 60a fuse, is their any way (other than uprating the cable and the fuse) that I can protect the main fuse from blowing, ie:60a circuit breaker, if I did fit this would the fuse blow first or would the circuit breaker trip?
Thanks

If your 60amp main fuse is blowing, a 60amp main breaker will perform the exact same way. My assumption is that your home has a 60amp service, and we're not talking about a 60amp individual circuit. Strange that the main is blowing...Normally the individual branch circuit's overcurrent device will blow/trip before the main does. The only way for the main to blow/trip is for a number of branch circuits to draw a combined total in excess of 60amps, none of them exceeding their own amperage limits.

If we're talking about the main, a service upgrade (perhaps 100, 125 or 200 amps) is very possibly in order.

You must cut down on your usage big time, or have a service upgrade. You will need a calculation done if you want to anyways.

The breaker will just trip.

What do showers have to do with it? We really need more information here.

When was your house built?

I don't think the OP is in the U.S. or Canada. I do believe he/she is in the U.K. Think about it: the OP built an "extension". And they were curious if it would be better to "fit" a new circuit breaker. I'm betting Brit.

Thanks to everyone who replied, it looks like I will have to fit a 60a circuit breaker at least I can reset this myself without having to call someone to refit the fuse.

I guess 60 amps goes further over there since everything's 220. I saw some pictures of UK panels and they are tiny compared to a modern US-NEC panel with all the dozens of required dedicated circuits.
