If you’re electricity connections  a new house or developing a housing development and want to connect electricity, you’ll need to apply to a energy supplier for a domestic supply agreement. Your energy supplier will contact ESBN to arrange your connection. ESBN operates and maintains the network. This article explains what you need to know about your electricity connections, including how to connect and disconnect.

The electricity distribution system consists of two kinds of wires. One of them is called phase and the other neutral. The function of the phase and neutral is to transfer electric power from the network to your home or commercial premises.

Single-phase connections are intended for domestic supplies and residential homes because they require less electricity. Unlike three-phase connections, single-phase connections only use two wires. A single-phase power supply doesn’t work as well with units that require more than 5 horse power. Three-phase connections have four wires that make up a complex network that transmits maximum power. Hence, they are used by large machinery.

Electrical continuity between wires is essential for electrical safety. When the continuity is lost, a spark may ignite the insulation and damage or even destroy the conductors. This is why it’s important to check the continuity between wires with an electrical tester.

Some connector housings are designed with locking mechanisms to prevent inadvertent disconnection or poor environmental sealing. These designs include locking levers of various sorts, jackscrews, screw-in shells and push-pull connector systems. Some of these locking mechanisms are also tested in environments such as physical shock and vibration, water spray, dust and other contaminants to ensure that they are effective.

As threats to people and buildings increase from criminal acts and terrorism, security measures become more sophisticated. Bollards are a versatile solution to thwart hostile vehicle attacks (HVM) by acting as both visual barriers and physical protection from vehicles. Whether they’re used as standalone applications or covers for steel-and-concrete security posts, these durable and attractive designs allow for access while deterring vehicles from entering sensitive areas. They’re available in multiple sizes and styles that meet different security ratings, as well as illuminated and non-illuminated options.

Traditional Bollards security are typically made of cast iron, and provide a timeless aesthetic that blends with most architectural settings. They’re a popular choice for regulating traffic in urban centers and public spaces, preventing vehicular intrusion and controlling access during specific hours. They can also be used in private parking areas, as a barrier for underground garages, and to protect high-profile buildings from attacks.

For a more modern approach, retractable bollards raise to prevent vehicle entry and then slide back into their ground receivers to permit passage. These are ideal for areas where a temporary blockage is needed, such as during events or during construction. They’re also a common replacement for lift gates at access points like parking garages or rail crossings.

For the highest levels of security, crash-rated bollards are designed to withstand multiple waves of vehicle attack. These are often used in governmental facilities and buildings to guard against terrorist attacks. They’re installed far enough from the building to prevent penetration and create a safe distance for people to evacuate in the event of an incident.
