Why do I need a bath ground: how to do the job

Bath - a place where people need to relax. Therefore, there must be comfortable and safe. Important safety factor is the protection voltage. You'll be safer if the ground the bath. We shall understand together, why do it.

Why do you need to ground the bath

As we know from physics, electricity always goes to where the least resistance. For current flow required closed circuit. If we take one hand "0", and the other phase conductor body becomes the electric charge. In this case, the current will flow right through most of the organs, including the heart.

Important! Even momentary exposure to electricity is dangerous, because it can cause an arrhythmia or stop the functioning of vital organs.

Grounding creates a potential difference that will secure interaction with electrical appliances. Due to the superconductivity current will keep it in the "land," and not through the human body.

In a modern apartment a plurality of electrical devices. Therefore, some devices, especially defective, can create stress on the body. This is dangerous in that the metal (especially wet) is an excellent conductor.

In only one bathroom it is often up to five appliances whose surface may be energized. The source of the danger of becoming an ordinary dryer or a washing machine.

Unsafe poorly insulated wall outlet or extension cords. Grounding should be in each bathroom, especially if there is a socket.

Reference. In Soviet times, the work was carried out with the help of steel pipes. However, the modern plastic equipment does not allow it. Therefore, in many apartments and doorways are special circuits.

How grounded are different types of baths

Depending on the type of bath and the material from which it is made, it is necessary to perform the procedure in different ways.

As a material effect on the operation

• Iron and Steel - excellent conductors, so such bath necessarily grounded. To this end, in some (especially older) models on the leg hole is drilled. There is inserted a special jumper, and wire away from her. In modern cast iron baths is a special tab, from which you need to let the cable.
• acrylic items They are not guides, but they can accumulate static electricity.
• Many models have steellegs or frameWhich necessarily need to protect. It is sufficient to couple the turns of the core wire, which is then allowed for steel pipe or a "ground."

What is needed for work

Attention! To avoid accidents, keep in mind the isolation of the contacting surfaces, and wires.

For electrical work will require the following set:

• The wire.
• Wrench, screwdriver for fixing cables.
• Multimeter for measuring the phase and voltage.
• Flashlight remedies.

If the old-fashioned bath and has no special clamps, You may need to drill or a drill.

Important! Each instrument must have a dielectric handle. Make sure you have insulation, or when it is connected there is a risk to get the current rank.

It is also necessary to take care of personal safety equipment (rubber gloves). You need to work only on a dry surface.

Completing of the work

For security at each entrance there is a ground loop, which you can connect to in a cabinet.

Important! The wire must be no less than 6 mm.

• Connect the bath and the grounding circuit is made through a box of potential equalization. She should be in a dry place inaccessible to children.
• The cable should be connected with the first metal bath surface, and the other end to the adjustment box. After this box is connected to the grounding circuit separate wire.

Important! Each device must be grounded separately. Consistent grounding dangerous. Each wire must be separate from the device to the bath or equipotential box.

Secure the bathroom can also be through a common ground of an apartment or house.

helpful hints

• connect the wire possible through the leg, a special clip or the self-drilled hole (if the bath is too old).
• Grounded recommended not only a bath, but other devicesFor example, a washing machine or sink. (This is especially important if the body is in direct contact with electronic devices).
• For greater security, can activate a residual current device (RCD). Usually it is installed in each room and in the case of a short circuit de-energizes it.
• For greater safety and convenience of the ground better to use special terminals. They are isolated, that will protect and during connection and during disconnection of wires.
• When if not terminal, the junction is better to cover with tape or other dielectric.
