NEW TRAINING COURSE SCHEDULED for Simple Circuit Calculations for Basic Electrical Installations

Friday 22nd October, £180 + VAT


This one-day course is intended for practising, experienced, electricians who undertake new installation work in domestic premises, where responsibility for design and construction are undertaken by themselves. The course will cover the procedures for designing simple final circuits to meet the general requirements within the scope of the IET On-Site Guide covering:


  • Maximum demand and diversity

  • Selection of types of cable for particular uses and external influences

  • Sizing of conductors for circuits based on:

    • Current carrying capacity

    • Voltage drop

    • Thermal constraints

  • Cable capacities of conduit and trunking

  • Methods of support for cables, conductors and wiring systems


Whilst the course focuses on domestic 100A electrical installations, the design principles can easily be extended to three phase commercial and industrial circuit design, covered in more detail in the 2396 Design and Verification course.


Completing this course will greatly assist delegates who intend to undertake the City and Guilds courses such as the Electrical Vehicle Charging Equipment Installations (2919); Inspection and Testing (2391) and the Design and Verification of Electrical installations course (2396); both these courses require circuit design to be undertaken.


Additionally, operatives undertaking periodic inspections (EICRs) of electrical installations will find this course of enormous benefit when assessing installation reference methods and circuit compliance with BS 7671, particularly when the initial circuit design has been altered over time.

From 19th July 2021  -  Although the legal requirement to wear a face covering has ended, the government expects and recommends that people continue to wear a face covering in crowded and enclosed spaces, so we are encouraging our delegates to continue please when entering the building and walking around within (except for those who are medically exempt). As always, the health and safety of our delegates and staff is paramount.  They may be removed once you are sat at your desk.  This will be subject to government review.
