Landlord Electrical Safety Certificate: Surge Protective Devices (SPD)

Landlord Electrical Safety Certificate is also used to protect sensitive electronic devices connected to equipment such as computers, televisions and washing machines. Security Circuits such as Fire Detection and Emergency Lighting Systems Devices with sensitive electronic circuits can be vulnerable to temporary overvoltage damage.

The effects of power surges can lead to immediate failure or damage to equipment that occurs only for a specific period of time. SPDs are usually installed inside consumer units to protect electrical equipment, but there are different types of SPDs. Other incoming services such as phone lines and cable TV. Landlord Electrical Safety Certificate is important to remember the protection of electrical equipment only, not other services. This can allow transient voltage to enter the facility.

There are three types of surge protectors:

• Originally, Type 1 SPDs such as the main switchboard were installed.

• Install SPD Type 2 on the sub-distribution board.

• (Compact SPD types 1 and 2 are available and are usually mounted on consumable units.)

• Type 3 SPDs are installed near the protected payload. Must only be installed as an add-on to Type 2 SPD.

If you need multiple installation protectors, Landlord Electrical Safety Certificate need to be adjusted to function properly. It is necessary to check compatibility with products offered by various manufacturers, and installers and equipment manufacturers need to advise on this.

What is a transient overvoltage?

Temporary overvoltage is defined as a short-term surge caused by a sudden release of previously stored energy or by other means. Temporary overvoltage's can occur both naturally and artificially.

How do transient overvoltage's occur?

Artificial moments appeared depending on the switching of motors and transformers and the type of lighting, but until now there was no problem with domestic equipment, but recently the equipment has changed with the advent of new technologies such as electric vehicles. Charging air / ground heat source heat pump and fast-controlled washing machine This increases the likelihood of crossovers occurring internally.

Temporary overvoltage's are usually caused by indirect lightning. This tends to be caused by a direct lightning strike on an adjacent power or telephone line. It causes a temporary overvoltage transmitted along the line and can cause serious damage to electrical equipment and related equipment.

Do I need to install the SPD?

In the current version of IET Wiring Rule BS7671: 2018, you need to get temporary overvoltage protection because the effects of overvoltage can be as follows, unless there is a risk assessment:

• Leads to serious injury or death; or

• Leading to disruption of public services and / or damage to cultural heritage; or

• Leads to suspension of commercial or industrial activity; or

• It affects many people in one place.

• This regulation applies to all types of buildings. This includes residential, commercial buildings and industrial plants.

Landlord Certificates London: Earlier versions of the IET wiring rules had the exception that some homes were not included in the surge protection requirements, for example if underground cables were installed. It was deleted. This is a requirement for all types of buildings. This applies to all new buildings and properties with new connections, including a single condominium.

The IET wiring rules are not retroactive, but make sure that the modified circuits are consistent with the latest version as the work is done on the circuits included in the equipment designed and installed in the previous version of the IET wiring rules. EICR Report London needs to do it. This is only useful if the IET routing SPD is installed to protect the entire installation.

It is up to you to decide whether to purchase SPD equipment. However, you must provide your customers with sufficient information to decide whether to remove the SPD. The decision should be made after estimating the cost of the SPD device, which can cost hundreds of pounds, based on safety risk factors. Compared to the installation cost of electricity and related equipment such as computers, televisions and necessary equipment (such as smoke detectors and boiler control systems).

Surge protection can be installed on existing consumer units. can be installed in an external cabinet adjacent to an existing consumer unit if there is adequate physical space or if there is not enough space. Landlord Electrical Safety Certificate is also advisable to check with the insurance company. This is because some policies may require your device to be SPD protected or not pay in the event of a claim.
