Product Information

Next, re-tighten all the terminal screws, ensuring that all wires are correctly fitted and securely held in place. Do not overtighten.

Attach green and yellow sleeving to the bare earth core on the new cable and tighten the terminal screws. Answer: Finding the size of your wrench is pretty easy. Multiply the bolt number of your wrench by 1.5. The number you get is the standard size for your wrench. Final Word The Subject of CE marking has been fraught with partial understanding and confusion. We felt a brief outline of what is a complicated political, legal, commercial and technical subject might help clarify matters for our customers.

Firstly, all electrical works must comply with IEE Wiring Regulations 18th Edition. The Regulations apply to the design, erection and verification of electrical installations, also additions and alterations to existing installations. In a suitable location, cut the ring or radial cable in half using some wire cutters. Estimate how much outer sheath needs to be stripped to allow the inner cores to reach the terminals and strip it away for both cut ends, and also for the end of your new supply cable. Next, screw the base of the junction box to the side of an adjacent joist, or to a batten nailed between joists. It will then be within reach of the cut ends of the main cable. If plasterboard, use a stud detector to detect any horizontal studs and if there are any, mark and cut the face of the plasterboard out either side of the stud. Notch the stud out to the depth of around 15mm using a chisel.The spur must be connected to the existing circuit using the same size and type of cable as used in the main circuit you’re spuring from. Normally 2.5mm twin and earth Works carried out outside of a ‘special location’. This means any work in the following rooms is non-notifiable: Kitchens, living rooms, bedrooms, porches, hallways, gardens, loft spaces and dining rooms. You have a legal duty of care to anyone visiting your home. In fact, you can be prosecuted if a visitor is electrocuted when using an electrical item you have worked on. Part P of the Building Regulations states that any electrical installations must be carried out by a competent person. The following tables are intended to aid cable selection by showing applications and specifications of the cables in the catalogue.

In this case you can cut a small section out the face of the plasterboard and notch the timber stud with a chisel, run the cable around it and then repair the hole. If you have had to make any holes then they will need to be repaired. See our project here on repairing holes in plasterboard for more help. Then connect the cores of the spur cable to the matching terminal – live to live, neutral to neutral, and earth to earth. Remember to add green/yellow sleeving to the bare earth cores. This table cross references many popular cable types against their appropriate cable group to aid the selection of an appropriate co-axial connector. Here, we’ve discussed how to convert metric sizes to SAE ones. Follow this table and you won’t have to take the hassle every time.Designed originally as a tightly specified co-axial connector for low power RF applications, the BNC has become the connector of preference for many communications, video and, until recently, computer network installations. The cables to and from any spurs you connect must be protected by a conduit of some kind; be it on the surface or buried in the wall The SAE measurement system is slightly complicated. It’s used more prominently in the USA and nearby regions. Here, the SAE measurements are used instead of the metric. It can be a bit challenging to navigate.

Alternatively you can again lift some floorboards and come up through the cavity from the base. In either case you will need to fish the cable through. Find out how to do this in our fishing electrical cables project here. These colour codes are offered as guidance in allocating circuits and investigating existing installations. There are also rules that govern the length of ring and radial circuits that limits the length of cable you use, no more than a floor area of 100 square metres, and long spurs can exceed those limits To ensure that no other spurs exist, the safest method is to find the supply cable for an existing ring main and then tap into this and take a feed using a 30amp junction box. This way you know that there are no other spurs present.
