Rated 5 out of 5 by from Wylex wired fuse to MCB swap I previously replaced my wired fuses with Wylex MCB type breakers. These are a god-send when all your circuits are well loaded or a bulb blows. So easy to reset the power. I have upgraded the cable to my workshop and hence bought a 40Amp breaker to replace the original 20Amp device. A replacement consumer unit will be purchased soon, but these MCB's are really useful on old systems.

Rated 5 out of 5 by from Wylex 40A MCB Shower upgrade, installed this MCB in less than 20 seconds, worked first time as you'd expect from Wylex. These babies are life savers!!! Customer was over the moon not having to pay labour and costs of a more expensive consumer unit upgrade.

Answer: 
Hi,
There are a number of factors that affect the maximum shower rating including the size/type of cable used, length of cable run etc. A qualified electrician should be contacted for an accurate assessment of all these elements.
