I have 2 similar questions:
- I have to replace an electric instant shower due to a faulty solenoid and the instructions for the new shower state that I SHOULD have an RCD as part of the consumer unit or separate (between the consumer unit and pull cord isolating switch). In my current set up I do not have an RCD. The consumer unit is an old Crabtree type (trip switch but not with RCD) and i am told by a local supplier that they no longer make replacement switches that encorporate RCD. Since the manufacturers are only saying i SHOULD have an RCD, can anyone advise me of the dangers and necessity if I dont. I have used electric showers for many years without one.
- A family member has a similar set up (not Crabtree but with a replacment MCB installed in an old unit). Again the shower is not protected by an RCD. They may be selling the house in the new year. Will this omission hamper/ prevent the sale. Should they get an RCD installed. I am aware you can puchase shower upgrade kits. If the work is carried out after 1.1.05 by a qualified electrician will they need this new P form and is there a cost implication?
Many thanks. pete t
