Today grounding bathroom has become an urgent topic.Before grounding in the house has not been done because it arose such a need.Over time, this issue has become acute, as in every bathroom there are many metal objects and electrical appliances.The source of increased danger, by the way, is itself a bath, so grounding the bath - a guarantee of your safety!
What grounding ↑
Usually, modern electric appliances has a metal groove to commit ground.Grounding is a special protection that takes electricity when a power on the device, and then takes it into the ground.Everyone at least one slightly "bumped" on the body of electrical equipment.It is often the case when working with a computer, washing machine or hot water, when the sample of PETN old water tank passes through an e
All this is, as you know, because our electrical wiring in the apartment, and in particular the bathroom, designed without taking into account the respective safety measures.But when the earth current breakdown on the body are not felt.It is also used for grounding lightning protection purposes and to prevent the negative consequences in the event of a lightning strike.
The urgency to protect ↑
Water - excellent conductor of current, so the electricity and water form a very dangerous combination for a man.Bathrooms for this reason are known as the most dangerous places in the house.
Where there is too much production and installation of metal pipes in combination with high humidity, to avoid accidents should be most strictly adhere to the rules of wiring.
metal objects that are not related to electricity (sinks, drains and water pipes, the pipes of the central hot water radiators, baths) can lead to fatal consequences if work fuse or other fuse.Thus, many are interested in and how to make a grounding in the bathroom and to prevent the appearance on the metal components of the hazardous voltage installation.
Previously, this problem was solved as follows: the body was connected to the bath water, or sewer standpipe.And today, to do so - our own peril!If the neighbors below within their own apartments will change the water standpipe steel or cast iron sewer riser installation of the plastic, it is - is not earthed bathroom.This increase in the area of the capacitor with all the consequences ensuing.
Terms device ground ↑
In accordance with the rules of the wiring is necessary that the bath was connected with a special connection to the grounding bus, which is located at the input distribution panel.This connection is called a ground jumper.And to carry out this procedure is necessary in any bathroom, regardless of the electrical equipment, which is located indoors.
Grounding old-style baths ↑
Many apartments are still fitted the Soviet baths.If the bath is old-fashioned, its ground connection must be done as follows.Drill a hole in the leg of the bath and by means of nuts, bolts and washers attach the grounding jumper.
stranded conductor is screwed to the foot bath, and on the other hand - to a special valve, which also connects to all other wires of metal objects in a room - pipes, drains, priborov.Raspredelitel housings can be mounted on a bathroom wall in an arbitrary location.But in any case it is necessary to bring to the common ground bus panel, which is located at the entrance.
If the cast iron bath apartment ↑
Modern metal baths are made with a special lobe ground.And grounding iron bath looks like.By lobe ground need to connect the "ground" wire exposed portion of the cable is clamped between the washers previously using the nut and bolt.
If the bathroom is installed electric shower with instant hot water or a water heater, it must also have a sound grounding jumper, made in the form of joining metal components - housing with grounded pipes.
Ground acrylic baths ↑
present trend of the 21st century - a bath of acrylic.These baths are light and not too expensive.They, like other products in need of grounding, despite the fact that acrylic is an insulator.Firstly, two kinds of acrylic fiber is - cast and extruded.Last bad material keeps its shape, and bathtubs made of it, necessarily completed metallic frame that requires grounding.
Secondly, the grounding of acrylic baths is carried out to remove static electricity: if you type in the water bath of a dielectric acrylic, it is still an element of the statics will be present.And if you have an area of acrylic bath is not small, it is able to accumulate and did a great electric charge.
Ground newfangled "Jacuzzi» ↑
stunning success today are the bath with electric filling - Jacuzzi.It works either a whirlpool bath by electricity.It must be connected to the mains that has a voltage of 220 ± 10% W and frequency of 50 Hertz.
to connect the bath requires a separate grounded sockets - special outlet for bathrooms with lockable plastic shutters Fork and a third connector, which acts as a grounding.These sockets do not let water get inside the spray and do not cause a short circuit, so they are called water proof.
rosette made to install on the wall - at an altitude of close to 30 centimeters from the floor or 50 centimeters from the outer side of a Jacuzzi with a view to prevent the ingress of water.Eyeliner perform separate wire in double insulation to the recommended cross-section of 2.5 mm2 3.
avoid damage to the electrical equipment, caused by surges, you need to install the machine, designed for a load of 16 amps, and the RCD, which has a value of 0.03 A. Differential Installation of the machine and operate the RCD is the bathroom.
Attention!It does not use the hot tub with a socket that has no ground contact.Also, you can not ground the bath by heating, sewer and water facilities.It is strictly forbidden to carry out work related to maintenance, when included in the electricity network the bath and use the hot tub with a damaged electrical cord and a ground fault.
Choice and wire ↑
wiring rules determine the size of the conductor to be used as a grounding jumper in different cases for the purpose of the minimum costs of installation work.The house is made to use a hard stranded cable, which has a cross-section of 6 square millimeters, in green with a yellow PVC insulation.This cross section is large enough to provide electrical bath.If using such a wire is connected to the heated bath of running water, the connection should be done through automatic overcurrent protection.
In most cases, the position of the economy for the grounding electrodes are choosing steel, although allowed to use steel copper shell or even copper.The length of the grounding cable should be at least 2 meters.However, one should remember that the shorter the cable, the less chance of it breaking.So you should think carefully about the time proximity output wiring for electrical equipment.Besides grounding should have a coating that degrades the electrical contact.
aesthetic reasons it is recommended to lay the jumper panel screen for bath, wash basin in the cupboard or under the floorboards.You can also tuck the wires under the plaster or voids inside the walls as a normal electrical wiring.
Regarding the need for grounding the bathroom there are different opinions, but if you think about your health and safety of care, better not to neglect this aspect.To avoid electric shock, which is caused by contact with the bath, it is necessary to ground.Indeed, in the case of force majeure only grounded preserve human life.
