Maintenance courses delivered Online

A five day Refrigeration Electrics Maintenance course aimed at anyone involved with refrigeration, air conditioning and heat pump electrical control systems. The Refrigeration Electrics Maintenance course covers the three elements which are common to most refrigeration and air conditioning systems, namely, protection, control and motors. For example, a typical air conditioning split system will have protection provided by the fuse in the fused connection unit, and further protection provided to the cable feeding the fused connection unit, probably by a circuit breaker, control provided by thermostat and time clock etc… and motor driven fans and compressor. During the Refrigeration Electrics Maintenance course emphasis is also placed upon the applicable wiring regulations to ensure the constructed system is compliant with BS7671:2018 The aim of the Refrigeration Electrics Maintenance course is to provide enough knowledge to allow maintenance and fault finding to be safely and effectively carried out. The Refrigeration Electrics Maintenance course comprises of: Essential Electrics Module City and Guilds 2382-22 Level 3 – 18th Edition Wiring Regulations Refrigeration Electrics Module The Refrigeration Electrics Maintenance course costs include examination entry fees.

Day 2 Proximity devices, limit switches and proximity switches, various types, principles of operation and uses Practical workshop, gaining an understanding of typical connections of various proximity devices and the range of available supplies catered for, voltage levels and current type Development of a typical simple control system using push buttons, proximity devices, relays and indicator lamps. Day 3 Protection against overcurrent Protective devices, various types, suitability and uses Earthing, including principles of protection against indirect shock Undervoltage protection. Day 4 Cable and core termination techniques, including crimping and soldering Practical workshop terminating YY, SY, SWA and MICC cable Testing, basic principles of circuit protective conductor testing and insulation resistance testing, instruments used and expected values Practical workshop testing cables terminated previously and testing cables with faults on test rig. Day 5 Fault finding, safety precautions and principles Practical workshop on fault rigs Root cause analysis PPM and maximising uptime

At the end of the 5 days, Learners will attain an RQF Award in the requirements of FD&FA systems for non-domestic buildings BS 5839-1: 2017.

This is a gateway course for all further learning in FD&FA systems.

Course Description: The 18th edition course is a 3 day short course aimed at anyone involved in the design, construction and inspection and testing of electrical systems, also a nationally recognised ‘must have’ qualification for companies seeking to recruit electricians. It is intended to introduce the candidate to a working knowledge of the Wiring Regulations along with a brief overview of the Electricity at Work Regulations covering their statutory duties. Previous knowledge of the regulations is not assumed, however, a fundamental knowledge of electrical principles is assumed. Please be aware that the Wiring Regulations course is not designed to teach you every regulation in the book but it will teach you the best practices on how the reference the latest regulations as you would on the job. As such key topics currently covered on the 17th Edition will still be included. We have been delivering Wiring Regulations courses for many years and although it is mainly theory based you cannot beat real training in a real classroom. By training with other people in your class you will benefit from being able to ask relevant questions as well as finding the answers to many questions from your fellow students that you may not have even thought of. The examination is a 2 hour multiple choice, open book PC based examination with instant results. The course cost includes examination entry fees. Focus: You will study the latest standard of the IET wiring regulations, including essential subjects such as safety, selection and erection of electrical equipment. There are 8 key modules and current amendments: Section 1 – Scope, Object and FundamentalsSection 2 – DefinitionsSection 3 – Assessment of general characteristicsSection 4 – Protection for SafetySection 5 – Selection and Erection of equipmentSection 6 – Inspection & TestingSection 7 – Special Installations or locationsSection 8 – Functional Requirements This course does include the latest amendments such as: Electromagnetic Disturbance Surge Protection Medical locations Operating and Maintenance Gangways Arc Fault Detection Devices (AFDDs) Changes to fire safety requirements in chapter 422, covering the design of electrical installations in industrial, commercial and multiple-occupancy homes, as well as new information for ‘protected escape routes’ Protection against over voltages Changes across Part 7: Special Locations This classroom based course will show, teach and perfect you on how to reference and use the book for situations that you will encounter while working in the field.

The Computer Maintenance & Repair Technician course aims to enable participants to diagnose and repair system level faults in computer-based systems at the foundation level.

This industrial electrical maintenance course is designed to enable candidates who have a small amount of electrical knowledge to gain recognised qualifications and skills to enable them to enter an industrial environment and work as a industrial electrician. The industrial electrical maintenance course will include a large amount of practical, enabling the candidate to install, fault find, design and wiring up control panels, using a variety of different methods. Industrial electrical maintenance course Aims The aim of the industrial electrical maintenance course is to provide solid foundations upon which the participant will be able to build and develop. Emphasis is given to providing the necessary skills, which will allow the participant to carry out routine electrical tasks. It is also made clear that a participant needs to identify and know their own limitations, allowing tasks to be carried out in a safe manner, not giving rise to danger.
