Into ensure the safety of human life has been specially designed system for grounding of electrical devices.This in itself is an earth grounding wire which in turn is connected to the grounding point and conductor.The conductor is located in the ground.In most cases, a steel wire or copper rod.Some experts recommend to be used as ground water networks, but it is not a reliable method.Thus, we consider in detail how to make a grounding in their own apartment.
In most cases, Khrushchev and brezhnevki have grounding system.The need for grounding occurs for the reason that the apartment is a large number of diverse appliances.If you want to protect it from damage, the best option to make ground with their hands.This will require the following tools and materials:
- Packing screws and washers.
- few meters of the core wire of suitable section.
- Metal rods.
- set of drills.
- metal strip whose section must be 50 mm2.
Ground household appliances
To start you want to replace the existing two-wire, three-wire electrical network.You need to buy sockets, which are designed for three contacts.As a rule, in an apartment without grounding set double-ended socket.If you are in an apartment completely change the wiring, then immediately route the three wires.To connect the grounding outlet must be properly define "zero".Accordingly, the three wires laid only one wire is + EV.The process of connecting one neutral wire connected to ground and directly to the second power supply.When all wires summed ends must be bare, removing their insulation.Further, he lived divided into two equal parts, between which is inserted a screw and washer.This wire must be secured with screws to a specially prepared site on the label.In most cases, the shields in place for fastening earthing indicate corresponding mark, it may be or Ground GND.
the mains outlet and without
Typically, grounding wire in an apartment there for electric ovens, washing machines, bath and so on.For some household appliances and stationary equipment grounding device just need the instructions.In private homes and cottages make the grounding circuit.How to make it, it will go further.
How to make ground loop
accumulation of static electricity can be not only in highly humid places.Therefore, to make the ground path necessary to ensure the safety of the electrical system in the house.In addition, it can do is not even an electrician.This device is made very simple: just put in the ground a few electrodes, and connect them with metal strips.
scheme grounding circuit
To ground the house is enough to three electrodes.You can use a crowbar.Previously it to be threaded and drill the holes to make the connection.Process for the production of earth loops in the following order:
- First dug holes for the electrodes.They must be positioned in a triangle shape.
- electrodes clog the maximum depth.
- between the three pins are dug small trenches.
- three electrodes are connected between the metal strip.
Building ground loop
As mentioned above, the strip should have a cross-section of 50 mm2.Then, the contour welding.Using bolt and nut attached to the circuit ground wire.
Ground acrylic and stainless steel / cast iron bath
There is much debate about the need to ground the bath or not.It should be noted that the bath is essentially a potentially dangerous object, so it is best to ground it.
Some throw the grounding wire from the bath to the sewer or water risers.But now, this technique can fail, for example, if the neighbors on the floor below the riser to replace plastic.For this reason, it is best to perform a ground on a dashboard, which has a special earthing bar.Consider the examples of ground iron / metal bath and acrylic.
grounded metal / cast iron bath.
Ground steel or cast-iron bath
Mainly leg drilled hole.Then attached grounding jumper with a bolt and nut and washer.
If the bathroom additionally installed electric water heaters, then they should also be grounded.
Ground acrylic baths.
Speaking of acrylic, it itself does not conduct electricity.But, despite this, the acrylic bathtub mogzhet collect a small amount of static electricity.Typically, such baths are mounted on a metal substrate, and which should be earthed.
Ground hot tubs
This also applies to the installation of whirlpool baths.Such devices necessarily connected to a single outlet, which should also be grounded.Moreover, these sockets are mounted at a certain distance from the whirl from the bathtub rim 700 mm and 500 mm from the floor.For security, you can install a separate panel automatic RCD, which will protect equipment from power surges.
for grounding acrylic and iron / metal bath should use stranded wire with insulation, cross-section of which must be equal to 6 mm2.Places ground must hide behind a decorative setting, so as not to spoil the appearance of the bathroom.
Grounding washing machine
Often the washing machine can punch shock.Especially often it happens in the process of excavation wet laundry from the metal drum.
scheme grounding washer
- One of the simplest methods of ground - setting the RCD and the potential equalization system.
- During assembly it is important to check the wire for insulation integrity.As mentioned above, it is better not to use for removing stray current water and sewer.
- When installing the electrical wiring it is recommended to make a separate socket for the washing machine.
- Do not use carrying.
- to connect the electricity to the machine is necessary to apply a three-wire cable.One of them will act as grounding.
As for the machine, then the washing machine is best to use the power of 45 A. If the outlet is waterproof, it can be placed in close proximity to the machine.If not, then the outside of this space.In this case, the need to extend the lead from the washing machine to the place of its powering electricity.In fact, this method of grounding of certain household appliances is carried out by the same scheme.Most importantly, it is right to execute initial work.
Tips and tricks
connection sockets with grounding
The following are basic guidelines and tips on making ground in the apartment:
- Grounding is recommended to all the appliances in the apartment.
- Each outlet in the apartment must be grounded.
- not permitted to connect equipment or grounding outlets with neutral when the device is in working condition.
- When connecting the power cable to temporarily turn off at the distribution board.
- for the performance of the production ground must use special ground terminal.
