Shower isolation swiching

[Brummiesparky]

Could any of you kind people clarify wether an isolator is required for an electric shower installation.
The manufacturers drawing shows one and quotes b.s. 7671 but I can't find anything in the rest
As a matter of fact I All ways fit one for safety reasons
Thank you in advanced

Well if the manufacturer recommends one be fitted, you'd be running foul of 134.1.1 and 5.10.3 if you didn't

510.3

Yes to isolator, yes to isolate earth faults from RCD, yes for future maintenance. Triton & Mira companies will love you so their engineers don't have to walk when dealing with a faulty shower unit under guarantee (guarantee is invalid unless you follow their install instructions). PS don't forget water isolation nearby!
