Equipotential Bonding For Metal Installations (photo by www.dehn-international.com)

Design of the earth-termination system for equipotential bonding

The electrical low voltage consumer’s installation requiring certain earthing resistances (disconnection conditions of the protective elements) and the foundation earth electrode providing good earthing resistances at cost-effective installation, the foundation earth electrode is an optimal and effective complement of the equipotential bonding.

The design of a foundation earth electrode is governed in Germany by DIN 18014, which, for example requires terminal lugs for the earthing busbar. If a foundation earth electrode is used as lightning protection earth electrode, additional requirements may have to be considered.

Equipotential bonding conductors (in future: protective bonding conductors) Equipotential bonding conductors should, as long as they fulfil a protective function, be labelled the same as protective conductors, i.e. green/yellow.

Equipotential bonding conductors do not carry operating currents and can therefore be either bare or insulated.

The decisive factor for the design of the main equipotential bonding conductors in accordance with IEC 60364-5-54 and HD 60364-5-54 is the cross section of the main protective conductor. The main protective conductor is the one coming from the source of current or from the service entrance box or the main distribution board.

Table 1 – Cross sections for equipotential bonding conductors

	Main equipotential bonding	Supplementary equipotential bonding
Normal	0.5 x cross section of the largest protective conductor of the installation	between two bodies	1 x cross section of the smaller protective conductor
Normal		between a body and an extraneous conductive part	0.5 x cross section of the protective conductor
Minimum	6 mm²	with mechanical protection	2.5 mm² Cu or equivalent conductivity
Minimum	6 mm²	without mechanical protection	4 mm² Cu or equivalent conductivity
Possible limit	25 mm² Cu or equivalent conductivity	-	-

In any case, the minimum cross section of the main equipotential bonding conductor is at least 6 mm² Cu. 25 mm² Cu has been defined as a possible maximum. The supplementary equipotential bonding (Table 1) must have a minimum cross section of 2.5 mm² Cu for a protected installation, and 4 mm² Cu for an unprotected installation.

For earth conductors of antennas (according to IEC 60728-11 (EN 60728-11)), the minimum cross section is 16mm² Cu, 25 mm²Al or 50 mm² steel.

Equipotential bonding bars

Equipotential bonding bars are a central component of equipotential bonding which must clamp all the connecting conductors and cross sections occurring in practice to have high contact stability; it must be able to carry current safely and have sufficient corrosion resistance.

DIN VDE 0618-1: 1989-08 (German standard) contains details of the requirements on equipotential bonding bars for the main equipotential bonding.

It defines the following connection possibilities as a minimum:

1 x flat conductor 4 x 30 mm or round conductor Ø 10 mm
1 x 50 mm²
6 x 6 mm²to 25 mm²
1 x 2.5 mm²to 6 mm²

These requirements on an equipotential bonding bar are met by type K12 (Figure 1).

This standard also includes the requirements for the inspection of clamping units of cross sections above 16 mm2 with regard to the lightning current ampacity. Reference is made therein to the testing of the lightning protection units in accordance with EN 50164-1.

If the requirements in the previously mentioned standard are met, then this component can also be used for lightning equipotential bonding in accordance with IEC 62305-1 to 4 (EN 62305-1 to 4).

Terminals for equipotential bonding

Terminals for equipotential bonding must provide a good and permanent contact.

Figure 1 - Equipotential Busbars R15 with Terminal Block System / Kit (www.dehn.de)

Figure 2 - Pipe earthing clamps (www.dehn.de)

Integrating pipes into the equipotential bonding In order to integrate pipes into the equipotential bonding, earthing pipe clamps corresponding to the diameters of the pipes are used (Figure 2, left and middle picture).

Pipe earthing clamps made of stainless steel, which can be universally adapted to the diameter of the pipe, offer enormous advantages for mounting (Figure 2, right picture). These pipe earthing clamps can be used to clamp pipes that are made of different materials (e.g. steel, copper and stainless steel).

These components allow also a straight-through connection. Figure 3 shows equipotential bonding of heating pipes with straight-through connections.

Figure 3 - Equipotential bonding of heating pipes

Test and inspection of the equipotential bonding

Before commissioning the electrical consumer’s installation, the connections must be inspected to ensure their faultless condition and effectiveness.

A low-impedance conductance to the various parts of the installation and to the equipotential bonding is recommended. A guide value of < 1 Ω for the connections at equipotential bonding is considered to be sufficient.

Supplementary equipotential bonding

If the disconnection conditions of the respective system configuration can not be met for an installation or a part of it, a supplementary local equipotential bonding is required. The reason behind is to interconnect all simultaneously accessible parts as well as the stationary operating equipment and also extraneous conductive parts.

The aim is to keep any touch voltage which may occur as low as possible.

Moreover, the supplementary equipotential bonding must be used for installations or parts of installations of IT systems with insulation monitoring.

The supplementary equipotential bonding is also required if the environmental conditions in special installations or parts of installations mean a particular risk. The IEC 60364 series Part 7draws attention to the supplementary equipotential bonding for operational facilities, rooms and installations of a particular type.

These are , for example:

IEC 60364-7-701 Rooms with bathtub or shower
IEC 60364-7-702 Swimming pools and other basins
IEC 60364-7-705 For agricultural and horticultural premises

The difference to the main equipotential bonding is the fact that the cross sections of the conductors can be chosen to be smaller (Table 1), and also this supplementary equipotential bonding can be limited to a particular location.

"It is unwise to pay too much, but it's worst to pay too little.

When you pay too much, you lose a little money - that is all...

When you pay too little, You sometimes lose everything,

Because the thing you bought or the service you acquired

was incapable of doing the thing it was bought or intended to do.

The common law of business balance

prohibits paying a little and getting a lot - it can't be done.

If you deal with the lowest bidder,

It is well to add something for the risk you run,

And if you do that,

You will have enough to pay for something better."

MEDICAL EXPERIMENT - MIRACLES WITH WATER

Japanese Sickness Association has published the following experiment with WATER.

They Claim 100% success for curing old and new diseases as follows:

1. Headache, BP, Anaemia, Arthrosis, Paralysis, Palpitation, Epilepsy and Obesity

2. Cough, Bronchitis, Asthma, and Tuberculosis

3. Meningitis and any other diseases connected with URINE and LIVER.

4. Hyper-acidity, Gastritis, Dysentery, Constipation, Piles and Diabetes

5. Any other diseases connected with Eye, Nose and Throat.

6. Irregular menstrual periods of women

METHOD OF TREATMENT AND MAINTENANCE:

1. Wake-up early morning and drink Four(4) glasses (160ml each) in an empty stomach.

Thereafter, no solids or liquids should be taken up to 45 minutes.

2. Normal breakfast can be taken after the 45 minutes time elapsed.

3. Nothing either liquid or solid should be taken for Two(2) hours after breakfast, the same as with Lunch and Dinner.

4. After Dinner nothing should be taken before bedtime or sleep.

Sick and old people will find it difficult to drink Four(4) glasses of water at an instant in the beginning, but, can increase

gradually to the recommended level in a short time period.

Experiment has proved that the following diseases have been cured on treatment of water for the period shown against them

a) Hypertension - 30 days d) Constipation - 10 days

b) Gastric Problems - 30 days e) Cancer - 6 months

c) Diabetes - 30 days f) Tuberculosis - 3 months

Those who suffering from Arthritis should try this experiment three(3) times a day for one(1) week and thereafter reduce to

once in the morning. For first few days you may experience to pass urine more than the norma, but no side effects.

THIS WILL CLEANSED YOUR BODY OF IMPURITIES AND WILL

PREVENT MANY TYPES OF DISEASES...

EXERCISE RELIGIOUSLY...

AS THE SAYING GOES "HEALTH IS WEALTH"

REMEMBER:

70% of our body is made up of water...

only 30% of our body is solid...

HEALTH IS WEALTH...

WHAT'S THE USE OF HAVING A BILLION

BUT LYING IN A BED - SICK

OR SUFFERING FROM AN ILLNESS.....

I WOULD RATHER HAVE A CLEAN BILL OF HEALTH FOR A BILLION.

WHEN YOU REACH THE AGE OF 35 EXERCISE IS A MUST...

WATCH YOUR DIET...

EXERCISE DAILY AND RELIGIOUSLY

TAKE YOUR MULTIVITAMINS TO SUPPLEMENT YOUR FOOD INTAKE....

FAMILY....RELATIVES....FRIENDS....HEALTH and most importantly TIME....

YOU ARE MORE BLESSED THAN OTHERS...

WHEN YOU HAVE BOTH YOUR EYES SO YOU CAN CLEARLY SEE

OTHERS HAVE ONLY ONE...OTHERS ARE TOTALLY BLIND...

WHEN YOU HAVE BOTH YOUR EARS SO YOU CAN CLEARLY HEAR

OTHERS HAVE ONLY ONE...OTHERS ARE TOTALLY DEAF...

WHEN YOU HAVE BOTH YOUR HANDS SO YOU CAN HOLD THINGS WELL

OTHERS HAVE ONLY ONE...OTHERS HAVE NONE...

WHEN YOU HAVE BOTH YOUR FEET SO YOU CAN WALK EASILY

OTHERS HAVE ONE...OTHERS HAVE NONE..

WHEN YOU STILL HAVE YOUR PARENTS...

OTHERS HAVE ONE...OTHERS HAVE NONE...

WHEN YOU HAVE CHILDREN...

OTHERS HAVE ONE...OTHERS HAVE NONE...

WHEN YOU HAVE A FAMILY...

SOME HAVE NONE...OTHERS TOTALLY ORPHANED

WHEN YOU ARE LIVING IN THE PHILIPPINES...A DEMOCRATIC COUNTRY..

THE WEATHER NOT THAT EXTREMELY HOT NOR COLD..

WERE PLANTS AND TREES GROW EASILY

SURROUNDED BY SEAS FULL OF FISHES AND NATURAL RESOURCES

WHEN YOU ARE OLD AND STILL LIVING WITH YOUR CHILDREN

IN SOME COUNTRIES OLD PARENTS AND PEOPLE

ARE LEFT IN THE "HOME OF THE AGED NURSING FOUNDATION"

WHEN YOU STILL HAVE YOUR JOB...WORKING IN AN AIR-CONDITIONED

ROOM..JUST CONSIDER THE CONSTRUCTION WORKERS DOING THEIR

HARD LABOR JOBS UNDER THE HEAT OF THE SUN...IGNORING THE

DANGEROUS ELEMENTS CONFRONTING THEM....

COUNT YOUR BLESSINGS...COUNT THEM ONE BY ONE...

DON'T THINK OF SAYING ANY UNKIND WORD...

THINK OF PEOPLE WHO CAN'T SPEAK,

DON'T COMPLAIN ABOUT THE FOOD YOU EAT,

SOME HAVE NOTHING.

DON'T COMPLAIN ABOUT LIFE,

PAINT A SMILE ON YOUR FACE

AND THANK GOD YOU'RE ALIVE AND STILL AROUND

LIFE IS A GIFT......

LIVE IT WELL......
