My present electric shower is presently powered by a 45 A Fused Connection Unit
near to the CU and then has a pullcord switch mounted near the shower . As part
of my bathroom renovation I am putting in 10mm cable and will either replace the
existing 6mm or juust leave it in place for future use to avoid any upheaval
,probably the former .
What I was wondering ( but not necessarily adopting) was whether the pullcord
switch is really necessary .Could the shower not be operated by using the switch
on the FCU when the shower was to be used ?....just a thought .
