We can supply ready-made electrical grounding leads for earthing conductive wall paint and other conductive coverings consist of a square of copper foil with a special conductive glue backing. A 2 metre length of thin wire is soldered and glued onto the copper foil. The other end is stripped of its plastic covering ready to connect to a suitable Earth/Grounding point.
We include a 5 cm square of aluminium foil tape to cover the copper foil when it is in place. This reduces the likelihood of its being pulled away from the wall.
Please Note: In some countries, external conductive paint, or metal surfaces, must be earthed by law. In the UK, it is not a legal requirement.
Laptop electrical earthing leads
High electric fields are often present in some laptop computers when plugged into their charger/power supply. These power supplies are often "double insulated", which means they do not have a safety earth connection. Unfortunately this means that the low-voltage supply to the laptop then "floats" to typically half the mains supply voltage (i.e. about 115 volts AC in the UK and Europe). There is not enough current to electrocute you, but it does expose you to high levels of electric fields of several hundreds of volts per metre at your hands and lap. This is high enough that many sensitive people report adverse effects from some laptops.
The earthing lead is designed to make contact between the mains earth and the metal chassis of the laptop, which minimises the electric fields produced by the laptop.
Please note that it does require the use of either one USB port and whilst the earthing lead is in place these ports cannot be used for their normal purpose.
We offer as standard the Laptop Earthing Lead with a 3-pin UK mains plug. We also offer an option without a plug, for countries outside the UK, which you can wire with your own local style of mains plug.
If you want to earth your laptop, but do not have the necessary metal connections at the back and wish to use all your USB ports for normal devices, then you will need one of these leads. It provides an integrated tag to connect your laptop earthing cable to, as well as a socket to plug a normal USB device into.
Many USB extension leads are unscreened or only partially screened, but this high-quality USB extension cable is fully screened along the whole length, which is necessary to be able to earth the laptop.
Please note that this does not include the laptop earthing kit (see above), which must be purchased separately.
