EDIS is the enterprise level electrical testcertificate software (including the latest 17th edition BS7671 2008 amendment no.1) used by large estates and property managers to manage their electrical inspection and testing.

EDIS ensures that all the information can be made available to the persons doing electrical inspection, testing, installation and maintenance EDIS aims to meet the requirements in Guidance Note 3: IEE Wiring Regulations, BS 7671.by providing the earthing and supply, boards and circuit details, historical periodic inspection certificates and facilities for a document library.

Guidance Note 3: IEE Wiring Regulations, BS 7671 provides a comprehensive list of the required information which should be made available to the person or persons carrying out the inspection and testing.

Assessment of general characteristics

(i) the maximum demand, expressed in amperes per phase (after diversity is taken into account)

(ii) the number and type of live conductors of the source of energy and of the circuits used in the installation

(iii) the type of earthing arrangement used by the installation and any facilities provided by the supplier for the user.

(iv) the nominal voltage(s)

(v) the nature of the load current and supply frequency

(vi) the prospective fault current at the origin of the installation

(vii) the earth fault loop impedance (Ze) of that part of the system external to the installation

(viii) the suitability for the requirements of the installation, including the maximum demand

(ix) the type and rating of the overcurrent protective device acting at the origin of the installation.

Note: These characteristics are also available for safety services such as UPS and generators.

Diagrams, charts or tables

The information below regarding the basis of the design must be made available. This is also a non-specific requirement of the Health and Safety at Work etc Act:

(x) the type and composition of circuits, including points of utilisation, number and size of conductors and type of cable. This should include the Installation Method shown in Appendix 4 (paragraph 8) of BS 7671

(xi) the method used for compliance with the requirements for protection against indirect contact and, where appropriate, the conditions required for automatic disconnection

(xii) the information necessary for the identification of each device performing the functions of protection, isolation and switching, and its location

(xiii) any circuit or equipment vulnerable to a particular test. EDIS provides the functionality to collect, manage and report on all this information
