When doing earthing for plumbing and the consumer units special attention should be paid to safety. It is important to make sure that earthing is performed correctly. So take a sit on your novogratz brittany sofa futon and continue reading.
How Does it Work?
Everything is quite simple. As it is known, any system may have faults. If, for example, you have such problems as cut wire or meltdown an appliance should have a fast way to earth for live power. The problems may occur if there is no way to earth. Certain safety rules should be followed. Otherwise, the results may be fatal.
Thus, homeowners have to ensure that there is a nice thick earth cable for all parts in their house that provides an easy path to the ground. There are gas, oil, and electrically heated boilers. It is not important what kind of boiler you have. Just be sure that any boiler is connected to live mains.
Faults may occur in the work of any boiler. If this happens boiler’s radiators will remain to be live. It can be explained by the safe construction of a boiler.
Important Things You Should Know
According to the safety requirements that all boiler manufacturers must meet, radiators have to be grounded.
According to the opinions of some electricians, it is necessary to have an ugly green and yellow wire that connects to the radiator with a big metal tag. So, anyone will be able to see it. However, it is not always the best way to solve the problem. It is necessary to earth it if it is attached to the boiler with a copper pipe. However, it doesn’t need to be earthed if a plastic grey pipe is used to connect it to a boiler.
Also, it is important to ensure that earthing is provided with an unbroken and continuous connection. Therefore, the earth strap can be placed on the other side of the wall or floorboards.
However, you must have access to inspect it anytime. It should be noted that a copper pipe has a continuous connection. This means that every individual radiator doesn’t need to be earthed. The easiest way to earth many radiators is to do this at the boiler.
The next step that you have to take is to earth the gas mains (they have to be earthed after the meter because the meter is a part of the gas supplier).
Water mains have to be earthed within 600mm of entering the house. The final termination is performed at the supplied earth on the incoming power cables.
Electricians will show you places, where you can touch it.
For safety needs, it is recommended to use a plastic pipe because it removes the large earthing surface in each room of the radiator. As a result, it becomes much safer. Despite the fact that this argument is opposite to what we have discussed here, it has to be taken into consideration anyway.
The point is that a person with dry hands is a lousy conductor of electricity. Wooden floor and carpet also create a barrier to power. This means that even if a person has a jolt it will not affect him/her significantly. This can be explained by the fact that the power doesn’t go through those materials perfectly.
Nevertheless, if there is a whopping great earth plate like a metal tub or radiator, then it may become a good route for power. So, the power can transfer from a person to earth. As a result, a person will get a fatal shock.
That’s why homeowners are advised to have plastic pipes in bathrooms and all over the house. People may worry about the fact that plastic pipes are filled with water. However, numerous tests have proved the fact that a plastic pipe filled with water is a poor conductor.
Also, it is important to note that plumbing fittings for baths are often provided with PFT tape (thread tape). They insulate the bath. Due to the fact that these fittings are produced from materials that have poor conductivity the bath or sink have to be earthed individually.
