Assessment of General Characteristics

Example
The installer must consider the use of the property and any special requirements of the users.

What it means
The needs of the occupier should be assessed for each property, layout and use will be different for an apartment or detached house.

Solution
Arrange the installation and equipment to suit the needs of the occupier and split circuits so that a fault on one circuit causes the minimum amount of problems.

Example
For the life of the installation, the design needs to cover the changing needs of the user in layout and loading.

What it means
Commercial properties may have a need to change requirements on a regular basis, the installation needs to be able to cope with these changes. Regular maintenance requirements should also be considered.

Solution
Circuits such as ring mains need to be designed and split to ensure continuity of service and minimum disruption to the business in the event of a fault. The use of RCBO’s for individual circuits is recommended vs grouping.
