5 (Zs ϫ Ia Յ U0). Example Type B The Zs for a 20-A type B can be calculated. 57 Ω 400 This calculation is fine for BS EN circuit breakers; however, there is a considerable number of BS 3871 circuit breakers still in use. The calculation used earlier is still used to calculate Zs. 1. 1 Circuit breakers Type Multiplier 1 4 2 7 3 10 4 20 Chapter | 4 31 Part 4 Example The Zs value for a 20-A type 1 BS 3871. 4 and 5 s do not need to be considered. The same calculation can be used for all types of fuse.

This is because the circuits are rarely loaded to their full capacity, and even if they were it would be very unlikely for all of the circuits to be in use at the same time. This is really the principle of diversity. Using the tables in guidance note 1 and appendix 1 of the on-site guide we can note the following. The shower, which would be classed as an instantaneous water heater, would have no diversity allowable. However, only the rated load of the appliance should be used, not the rating of the protective device.

6. Great care must be taken to ensure that any exposed conductive parts of the separated circuit and the equipment connected to it do not come into contact with any other earthed parts of other circuits within the installation. 10). 3 must be used. 2 must be fixed in a prominent position at every point of access, warning that the equipment must not be connected to earth. All exposed conductive parts of the separated circuits must be bonded together using insulated bonding conductors. 10 Low-voltage isolating transformer not connected to earth, must be connected to the equipotential bonding system.
