Arc fault Detection Devices or AFDDs are now a requirement in many properties, including HMO’s and care homes across the UK.
It is also recommended that they are installed on all socket circuits in your home. But what is an AFDD? And what does an AFDD do?
Quality Electrician are your qualified local electrician in Birkenshaw, Bradford. We are here to explain everything you need to know about AFDD’s.
Back to top1) What does an AFDD do?
An AFDD is a specialised circuit protection device that is installed on your fuse board/consumer unit. It is similar to both your miniature circuit breakers (MCBs) and residual current device (RCD) but provides a different kind of protection. An AFDD is designed to protect you from the risk of electrical fire caused by arcing or sparking. An AFDD is designed to detect any abnormal arc wave patterns and is able to distinguish these dangerous arc wave patterns from the everyday, normal arcing that can occur when electrical equipment is unplugged.
Back to top2) What is an Arcing Fault?
An arc occurs when there is an electrical discharge passing through the air as it jumps a gap in an electrical circuit. An arc fault happens when there is damage to wiring, for instance through rodent damage, or when there are loose connections allowing the electrical current to find its own path. The arc creates intense heat (up to 6000 degrees C!) which can burn through insulation and cause a fire. Arcing faults can develop quickly or over a period of time.
Back to top3) Why do I need an AFDD?
There are several property types where an AFDD is now legally required but if this is not the case for your property why should you add an AFDD? Installing an AFDD will, quite simply, keep your property safer from the risk of electrical fire. So much of the electrical wiring in a home is out of sight that without an AFDD, should an arcing fault develop, you may not be aware until it is too late. For many homeowners in Birkenshaw, installing an AFDD gives them the peace of mind that they are fully protected.
Back to top4) Where should AFDDs be installed?
According to the 18th edition of the wiring regulations, AFDDs must be fitted at the origin of any single-phase AC final circuits supplying socket-outlets with a rated current not exceeding 32 A in the following premises:
- Higher Risk Residential Buildings (HRRB) in practice this means a building that is over 18m or 6 storeys high
- Houses in Multiple Occupation (HMOs)
- Purpose built accommodation for students
- Care homes
AFDD’s are also highly recommended in buildings with thatched roofs, wooden buildings and anywhere with sleeping accommodation such as a bed and breakfast. Most reputable electricians will also recommend an AFDD is fitted in private homes as it provides the highest levels of fire protection and electrical safety.
