Surviving the current changes to the UK's working economy may mean now seriously looking to retrain on an entirely new career path. The current demand for green energy technology driving the renewables sector is set to increase as Government carbon reducing initiatives in both the private and public sector continue to be rolled out.Key to keeping up demand in the future growth in both consumption and supply will be the training of qualified electricians capable of being both a green energy assessor and competent systems installer.NVQ Electrical courses are the foundation knowledge learning for any individual who wishes to enter the industry. To get an idea of the basics you can train over a set number of days, or weeks and obtain a Diploma. Embarking on an entry level City & Guilds Electrical NVQ 2330 level 2 course prepares you with the necessary theory and practical skills to go on to the next stage to becoming a full-time qualified electrician, Electrical NVQ 2356 Level 3. Course flexibility even enables taking the syllabus over consecutive electrical weekend courses for those without time during weekdays.One of the key important areas of basic knowledge learning includes a property's consumer unit which controls distribution, in other words, the fusebox! It's when an electric circuit suddenly 'trips out' in a household that problems can get out of control, which can lead to serious risk of personal injury or even electrical fire damage to the property.Understanding the different types of circuit breakers and how each function is vital. Essentially, they are designed to trip and turn off power when any of the following dangerous situations occur:Circuit Overload - has more connected electrical load than it is supposed to have.Short Circuit - the hot wire touches another hot wire or touches a neutral wire. And if there is a break in a wire in the circuit.Ground Fault - when the hot wire touches the ground wire (bare copper) or the side of a metal socket box (because the metal socket box is connected to the ground wire).Circuit breakers are rated for different currents. A 15 Amp circuit breaker protects a 15 Amp circuit, but if 20 Amps of current start to flow through it because of too many appliances connected to the same circuit and on at the same time - even if in different sockets - then the circuit breaker trips to prevent overheating of the circuit. Short Circuits are caused by faulty wiring in the circuit or plugged-in appliance.Electricians often find 'fuse boxes' in dangerous states of neglect or bodged disrepair. Many are long obsolete and need to be replaced with modern RCD units. It is estimated that only 25% of consumer units in the UK include an adequate level of RCD protection! Since mid-2008, an integral part of any new installation will be the rewire or replacement of a consumer unit, as there has been a requirement in the UK Wiring Rules to provide RCD protection for virtually every socket-outlet and circuit in a domestic dwelling.The future work schedule of a fully trained and qualified electrician looks assured!
