Product Information

You can then re-tighten all the terminal screws, ensuring that all the wires are correctly fitted and securely held in place. Make sure you don’t overtighten at this stage. 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 Reached the point where you are unsure how to proceed? Please do not hesitate to call an electrician. Generally, the conversion is done from metric to the imperial system.If you’re savvy with the Imperial to Metric conversions, this might be easy for you. How did we arrive at today's typical values for cable impedances and what values will be suitable going forward?

The following tables are intended to aid cable selection by showing applications and specifications of the cables in the catalogue. The slightly easier and more straight forward method is to use a junction box. This is mainly due to the fact that you can choose your install location and ensure there is plenty of space so you’re not struggling to see when connecting things up. Next, strip 10mm or so from the end of each core wire for each of the 3 cables. Once done connect each wire to a terminal in the junction box, ensuring that the same core from each cable is connected to the same terminal e.g. all lives to one terminal, all the neutrals to another and all the earths to another one. 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. Dr. John Emmett discusses the characteristics a cable needs for use in high-performance digital video applications.

How to wire a socket

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. Information on the Digital Switchover and the phasing out of channel 69 as a licensed frequency for use in Radiomics. 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 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. Please note, if there is any sign of damage on the wiring, use side cutters and electrical wire strippers to trim the damaged wire, leaving 5mm of wire clear.

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. Next, strip 100mm or so from the end of each core live and neutral cable and then bend the stripped area in half. Place some earth sheath over the earth cable and then do the same for the earth. 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.If the faceplate is made of metal, cut a short length of earth core from 1.5 mm² cable and run it between the earth terminals of the faceplate and mounting box. Replace the faceplate. Step 4 The next job is to run the supply cable. From the location you’re tapping into the radial or ring circuit, leave a good 6 – 8 inches of cable for wiring the junction box. Make sure it’s clamped or held in place so it doesn’t get pulled away. Both the SAE and Metric charts are pretty common. In certain parts of the world, both systems are used extensively. If you’re from any such part of the world, knowing both is crucial for you.
