FEATURE fundamental requirements for labelling and exactly what symbols to use, and when. For example, Regulation 134.1.7 requires the provision of accurate warning signs where there is a significant risk of danger to the user and explains how and where these need to be displayed on the installation. Warning notice, periodic inspection and testing labels all have to be a particular size to meet current regulations. Tip 4: Changing rules Make sure you’re keeping regularly up to date with changing regulations too – they are constantly being reviewed and updated. For example, Amendment Number 3 came into force in January 2016, stating that all domestic consumer units must be made from non-combustible materials or metal – meaning electricians have to now make sure all labels offer excellent adhesion to these kinds of surfaces. Memorise this labelling checklist: ✔ ✔ ✔ ✔ ✔ ✔ Is this durable enough to last the duration of my installation? If handwritten, is this legible for others? Will the weather fade or alter the condition of the label? Do all warning labels clearly stand out? Is this the correct size label? Am I using the necessary symbols? Tip 5: Requirement vs. best practice Remember – wiring regulations are a minimum requirement. Best practice labelling requires a higher standard, so make sure you’re going above and beyond to create an organised, safe environment for yourself and those around you. A professional label printer, if you’re not already using one, can help you achieve this. Brother UK’s flagship PT-E550W is specifically designed to print clear, durable labels that can be used across different sites and components. Models come with a variety of built in templates, including warning and instruction labels, PAT test labels and notices to identify RCDs and cable wrap/flag. The IET Wiring Regulations: BS7671 The Institution of Engineering & Technology (IET) is the industry authority on electrical installation. BS7671 sets the standards for electrical installations, both nationally and internationally, and ensures electrical work meets the requirements of the Electricity at Work Regulations 1989. Gira eNet Easily controlling home technology via radio Gira eNet is the new bi-directional radio system for the intelligent networking and control of modern electrical installations. Functions such as light and blind control can be easily retrofitted and networked via radio. Installed switches can be quickly replaced or made radio- capable without having to prise open walls and lay cables. Radio switching/dimming top units, radio wall transmitters, and radio remote controls are available to operate the system. In addition, the Gira mobile gate also enables the entire system to be controlled using mobile end devices running the iOS or Android operating system. This allows blinds, lights, and pre-programmed scenes to be operated conveniently and intuitively via the Gira Interface when using WLAN at home. In the same way, the state of the lighting and blinds can be recorded and monitored at a glance. Additional information can be found at www.gira.com/enet.
