leesir_89 Posted May 23, 2014 Share Posted May 23, 2014 Our electric shower keeps cutting out mid-shower and doesn't stay on very long at all. It's currently an "Essentials 8.5" (Wasn't installed by us and don't know how long it has been there) Was told I need a new shower so I'm looking to get a 10.5 one from B&Q. Do I need an electrician or plumber to fit this and I know some new cabling may be required? Any info is much appreciated - Thanks. Link to comment Share on other sites More sharing options...

Make sure the shower has its own RCD on your breaker board and is fed by either 6 or 10mm cable. Most electric showers are pretty simple to change over but if you've any doubts please contact a qualified electrician. Link to comment Share on other sites More sharing options...
geared Posted May 23, 2014 Share Posted May 23, 2014 You need to check your wiring is man enough to take a 10.5kw shower. or just fit a 8.5Kw version as you know the wiring can take that. If you're not fiddling with the wiring than a plumber alone can fit the new shower if you don't wanna do it yourself. Link to comment Share on other sites More sharing options...
JOHN HABS Posted May 23, 2014 Share Posted May 23, 2014 A 6mm Twin & Earth cable along with a 32 amp breaker is ok for showers rated up to 7.5Kw maximum. If your cable is 6mm and the breaker is 32amp and your using a shower unit rated at 8.5kw, then that's the reason its cutting out - the cable and breaker are not big enough. An 8.5Kw shower requires the cable to be at least 10mm with a 40 amp breaker. Fitting an electric shower yourself is not particularly difficult job ( that is the plumbing part ) however, if your not familiar with the electrical side of things, then its advisable to employ an electrician to carry out the rewiring.

butlers Posted May 23, 2014 Share Posted May 23, 2014 Take the showerhead off , see it temp remains stable. Theres also a filter in the feed pipe,might be worth checking. Either way low flow can equal trip. PM sent Link to comment Share on other sites More sharing options...
Sam @ Dearne Posted May 23, 2014 Share Posted May 23, 2014 Not as straight forward as people make out. I would only put a 8.5 max on a 6mm cable. Where are the cable and water entry pipes, left, right etc...? You need to find a shower that has a similar footprint to your current one. Has someone tiled upto your current one, therefore leaving a hole in the wall so to speak. Do you know the diff between a 6mm and 10mm cable, i sometimes see 4mm cables.
