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.

what is the maximum rated electric shower that I can fit to a wyflex 32B MCB

Asked by: smudge52
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.
