1. When working on a Macerator you must ensure:

a. the appliance is disconnected from the consumer unit
b. it is turned off at the appliance
c. it is isolated at the consumer unit
d. it is turned off at the fused spur unit by the appliance

---------------------------------------------------------------------------

2. An instantaneous electric shower unit should be wired directly from the :

a. fused spur outlet
b. junction box
c. ring main
d. consumer unit
---------------------------------------------------------------------------
3. You would find a capacitor fitted to:

a. central heating pump
b. a solenoid valve
c. a consumer unit
d. an electric kettle
---------------------------------------------------------------------------

I could give you the answer to # 3, but I don't know about the other two. A capacitor is like a small battery. It charges and discharges in an electronic equipment. It could be in almost 99.9% of electric equipments. Therefore, the answer is (d). However, if by (c) they mean Consumer electronic Unit, the that could be too.
