A healthy circuit is one which contains a safe amount of electrical current flowing that does not exceed the intended design of the circuit, creates no excess heat and carries no risk of overload or electric shock.

Electrical equipotential bonding is one of the most important electrical safety aspects of wiring systems. The purpose of Equipotential Bonding is to reduce the chance of electrical shock, the risk of fires and explosions and to assist in circuit disconnection through low resistance earth path connections.

A TRIP SWITCH is a device that is contained inside an electrical enclosure such as a consumer unit, fuse box, or electrical panel. The trip switch can take various different forms and can perform a variety of tasks dependant upon type.

Ground Fault Circuit Interrupters are primarily used as an electric shock prevention device. They are designed to trip when tiny levels of electrical current go astray from an electrical circuit. They are far more sensitive than a circuit breaker as they are set to a very low trip level or around 6mA, that 6 milli amps or 6 thousandths of an amp (Unit of electrical current). Whilst this is extremely low, higher levels of electrical current can begin to cause harm to the human body.

With the ever-increasing number of appliances, chargers, and devices that we are plugging in to our homes electrical system many new homeowners are finding that there is an inadequate number of socket-outlets in their homes. Whilst there is no legal requirement for a minimum number of electrical outlets in the wiring regulations or building regulations, there is a recommended minimum depending upon the size of the room. An increased number of socket outlets will mean less reliance on extension leads reducing the risk of overloading extension cords, fire risk and trip hazards.

Rubber wiring has not been used in the UK since approximately the mid-1950s. Other countries may have used rubber wiring for a longer or shorter period than this. Whilst rubber wiring was ok when installed many decades ago, it was never intended to last until now and any black rubber cables that are still in use today are likely to be dangerous. As the rubber has aged it has become brittle and the slightest movement is likely to cause the rubber to fracture and fall away. This will leave bare metal wiring exposed, live to the touch, cables shorting out and a high risk of electrical fires.

Electric Vehicles (EV) are becoming increasingly popular in 2024 along with a growing charging network, but before making your purchase there are vital pieces of information that you need to know that you may not have considered. Such things as: What is the range on a full charge?

There are many situations we come across during our weekly work where we know that things aren’t right. This is one of those situations. We can see from the photograph that there is a large hole in the top of this electrical enclosure. The enclosure is also hanging off and the switch inside is mounted at an angle. Generally, this is very poor!

There are many place throughout our homes that electrical accessories are installed, floor level sockets, light switches halfway up the walls and pull cord ceiling switches. These are all common areas where one would expect to find such things. There are slightly more obscure places where electrical outlets might appear such as electrical sockets in harder to reach areas. A PLUG SOCKET IN CUPBOARD is a common occurrence in many kitchens throughout the UK but is it safe? Is it right? Is it ok?

Buzzing sounds from speakers can be very annoying and detrimental to your audio listening experience. Whether you're dealing with vehicle audio systems, computer speakers, PA systems, or home audio setups, there are common reasons for this. This article will guide you through various effective solutions to rid the buzzing noise, covering topics like grounding and earthing issues, electromagnetic interference, and the use of a ground loop isolator.
