Do I need an electric vehicle charger with automatic load management (ALM)? - With electric underfloor heating and power supplies to garden offices far more common, coupled with existing electric showers, ovens and hobs not every household can add a 7.4KW electric vehicle charger set to 32A (full power) which doesn’t have automatic load management (ALM). ALM is designed to safely adjust the maximum charging current being drawn by the electric vehicle (EV) to prevent the charging device being responsible for overloading the electrical service to the property. ALM typically uses a current transformer (CT) Sensor that is clipped to the main incoming power feed into the property. The maximum power consumption can be set within the EV charger and once installed and configured, the charger monitors the consumption. In the event that charging would exceed the pre-set limit, the in-built technology will reduce the EV charging current being drawn to protect the main cut-out fuse. This is one reason why we recommend and install the Hypervolt Home 3, but there are other benefits as this is an all-round great solution for residential properties, go to https://hypervolt.co.uk/ for more details. In order to use ALM its necessary to install both power and data cables so that the charger can monitor the load being drawn using the CT Sensor. Hypervolt Connect cable provides the solution combining both power and screened data into one cable, saving installation time and cost. Just like we used on the install of another Hypervolt Home 3 at a property in Sale, Greater Manchester installing the Hypervolt Connect cable, with a separate EV distribution board/consumer unit to include surge protection to the latest IET 18th edition amendment 2 wiring regulations.

Hypervolt Home 3 with automated load management (ALM) installed at a property in Reddish, Stockport using Hypervolt Connect cable for power and data, with a separate EV distribution board/consumer unit installed to the latest IET 18th edition wiring regulations. Hypervolt provide a dynamic solution by using the ALM to use the current available without exceeding the the main cut-out fuse, in this case 60A. To arrange a site survey and to discuss your requirements, call Cameron on m: 07853216468.

Wallbox Pulsar Max installed at a property in Withington, Manchester. The options to locate the charger were extremely limited.. Whilst larger than the Pulsar Plus which has been discontinued in the UK, the Pulsar Max is still relatively small measuring 198mm x 201mm x 99 mm, although some space is still required around the charger. Due to the age of the existing installation, a separate EV distribution board/consumer unit was installed ensuring safety and compliance with the latest IET 18th edition wiring regulations.

Consumer unit moved using a Wiska 818CUR Consumer Unit Relocation Kit and upgraded with a Wylex 13 way consumer unit with type 2 surge protection installed at a domestic property on the Fylde Coast and populated with combined arc fault detection, overcurrent/overload protection and residual current devices (AFDD/RCBO's) as the latest and safest solution was opted for by the client. Following Grenfell, arc fault detection devices (AFDDs) conforming to BS EN 62606 must now be provided on single-phase AC final circuits supplying socket-outlets with a rated current not exceeding 32A within higher risk residential buildings (HRRB), houses in multiple occupation (HMO), purpose-built student accommodation and care homes. Mandated within other countries AFDD's are recommended within the UK for all other categories of domestic properties, although this could change should production costs reduce as production / sales volumes of AFDD's increase and manufactures become more competitive. This installation was installed against amendment 2 of the 18th edition wiring regulations. For further information as to the benefits of installing AFDD's and how they work, please read the article linkedhttps://www.beama.org.uk/static/uploaded/e84e99ab-31e5-4e3f-90119f674de7bb48.pdf

Old rewireable fuse board change at a property in Burnage, Manchester after E-ON raised concerns with the customer following installation of a smart meter. A new Hager 8 way consumer unit with type 2 surge protection device (SPD) and populated with 6 RCBO's. This installation was competed to comply with amendment 2 of the 18th edition wiring regulation to include the new requirement from September 2022 to install surge protection device (SPD) within domestic properties. SPD's can prevent the spread of overvoltage in the electrical installations and protects equipment connected to it. The regulations states that “Protection against transient overvoltages shall be provided where the consequence caused by the overvoltage could result in: 1) serious injury to, or loss of, human life (for example. Hospitals and, care homes, or in the provision of home dialysis equipment); 2) failure of a safety service; 3) significant financial or data loss
For all other cases, protection against transient overvoltages shall be provided unless the owner of the installation declares it is not required due to any loss or damage being tolerable and they accept the risk of damage to equipment and any consequential loss.”
When considering whether or not to install SPD during a new consumer unit upgrade within a domestic property, it becomes clear very quickly that the cost of the connected equipment such as computers, widescreen TV's, or EV charger points by far exceeds the marginal cost of the SPD device or devices, and therefore could lead to significant financial loss when not installed. More information on SPD's from Hager can be found https://hager.com/uk/support/regulations-18th-edition/surge-protection

Old plastic 'split board' with only half the circuits protected by one residual current device (RCD) was replaced at a property in Heaton Mersey, Stockport with a new 14 way Hager metal consumer unit comprising of 11 RCBO's and 1 MCB supplying a second consumer unit providing power and lighting to a loft extension with a new termination of the SWA cable and fire sealing. RCBO's combine the function of a residual current device (RCD) with a miniature circuit breaker (MCB) in one device to provide both overcurrent/overload protection and additional protection reducing the risk of a electric shock should a fault occur. Installing RCBO's on individual circuits is a good way to minimise any disruption should RCD's or MCB's operate. Under the latest regulations and requirements for the division of circuits, RCBO's should be used instead of a 'split board', even where two RCD's are installed to avoid power being lost to multiple circuits at the same time; where RCBO's are used, only the individual circuit affected should lose power when the device operates.
​

This installation was installed to meet the 18th edition wiring regulations, to include the requirement from an earlier edition (January 2016) to use non-combustible materials for the enclosure (usually metal) to help contain any electrical fire within the enclosure or cabinet and to minimise the escape of flames. Fire investigators have found that consumer unit fires are almost invariably found to be the result of poor workmanship or a lack of maintenance. At Aris Electrical we are acutely aware of these factors and go to great lengths to ensure our work is of the highest quality by being meticulous and paying attention to detail to ensure our electrical connections are correctly made. This includes tightening connections to manufacturer torque setting, making sure cable insulation isn't taken inside terminal connections so that proper contact with the conductor is made and ensuring all factory-installed connections are checked for tightness where required to do so by the manufacturer.
