Single hollow space ovens and not using a hob are more often placed on a 13a plug. Maximum hobs require their personal excessive current feed, however a few are available that comprise load restricting switching, and are designed to be run on a 13a plug.

An electric shower can be fed on its own high contemporary cable, fed from its own mcb on the rcd blanketed aspect of the cu. For greater statistics on electric showers, see putting in an electric powered bathe.
Filament lamp failures can journey mcbs, so fuses have a bonus over mcbs for lights circuits, as they rarely nuisance ride on bulb failure. (Much less touchy kind c and d mcbs can regularly be used to help reduce this hassle.).
With a nearby earth rod, the scenario is specific in that all circuits have to be rcd covered, due to the fact that a local earth rod isn't usually a sufficiently suitable earth on its personal to clear all earth faults. So rcds are used on all circuits even in older installations. A common alternative is to have the supply fed thru a 100ma time not on time rcd, the output of which is going to a cut up cu with rcd on one facet. This is not a really perfect association, as a huge earth leakage fault on the non-rcd side will motive entire electricity failure, and from time to time lack of ability to reset the energy.
With a provider supplied earth connection, the most not unusual historic association turned into a break up cu with a rcd on one aspect, and no rcd on the alternative. Usually the rcd aspect is used to deliver sockets and shower, with maximum different gadgets on the non-rcd aspect.
