We can also test the safety of electrical equipment in a domestic situation. Perhaps
you are concerned about an elderly relative or friend. Although this is not a legal
requirement, you can minimize the risk of accidents caused by faulty electrical appliances.
Tests are carried out using the very latest SEAWARD SUPERNOVA PLUS and EUROPA computerised
Pat Testers. TheSupernova can to test 110 volt and 240 volt appliances from either
110 volt or 240 volt supply, allowing us to test any appliance, with any supply,
giving us absolute flexibility in our testing procedures.
These days test procedures are often subject to review and change. Both the Supernova
and the europa can be upgraded via downloads direct from Seaward's website! so
our customers can be sure that their electrical appliances are being tested to the
very latest standards, using the very latest state-of-the-art test equipment.
The ELECTRICITY AT WORK REGULATIONS 1989 and HEALTH AND SAFETY AT WORK ACT 1974 puts
the duty on employers and employees, including the self-employed, to ensure the safety
of everybody at work. They require that, as may be necessary to prevent danger, all
systems shall be maintained so as to prevent, so far as is reasonably practicable,
such danger. This includes electrical equipment. The regulations apply to all places
of work including the entertainment industry and rented properties (including caravans)
etc. Regular inspection and testing is designed to protect you, the employer, your
employees and other people (customers etc) in the workplace, against the risk of
personal injury, fire, or even death from a faulty appliance during work or social
activities. The scope of the legislation is very wide and includes all portable and
transportable electrical equipment.
DEFINITION OF PORTABLE APPLIANCE
A portable electrical appliance is defined as any electrical equipment which is powered
between 40 and 240 volts and which is connected to the electrical mains via a flexible
cable/plug and socket (usually a 13 amp outlet). It does not imply that the appliance
is readily portable, only that it can be moved without unwiring. Portable electrical
appliances owned by employees are occasionally brought to and used in the workplace.
This policy applies to such appliances as if they were the property of the business.
Portable appliances are not just specialised pieces of electrical equipment that
require testing routinely. They include everyday appliances such as :-
Visual display units; Computers; Kettles; Hand Drills; Photocopiers; Fridges; Mobile
Phone Chargers; Vacuum Cleaners; Televisions; Video Recorders; Musical Instrument
Amplifiers and PA systems; Heaters; Church Organs and even PAT Testers!
The Code requires that in addition to user checks, formally documented visual checks
are routinely carried out.
Earth Bond Test.
Class I equipment normally conducted from 4A to 25A. This test is for checking the
integrity of the resistance of the safety earth connection
Earth Screen Test.
Used to test I T equipment (e.g. computers, copiers etc) which require a low earth
“screen” current of 100mA (Sometimes called business equipment or I.T. test). This
is to prevent damage to the equipment.
For class I and II appliances, this is normally conducted at 500VDC, with option
of applying a 250V test where mains input filters might give misleading readings.
Earth Leakage Test.
For class I and II appliances, used where insulation testing is not recommended.
The current flowing into the appliance via the supply cable, is compared to that
flowing out. Any difference must be leaking to earth, either via the earth lead
(class 1) or the case or other connection (class 2).
This is a very severe test and can cause damage to equipment. Flash tests are normally
only carried out to equipment that has been repaired or sustained damage.
Only when the test engineer is satisfied with the visual checks, is the appliance
connected to the test equipment. Modern computerised Portable Appliance Test (PAT)
Equipment is used for testing. This equipment is capable of carrying out all the
tests necessary under the IET Code of Practice. The test results are stored by this
equipment and downloaded to a computer, to provide accurate test result documentation.
The equipment used is regularly calibrated and is also checked for accuracy before
every testing session.
Disconnecting Computers and Sensitive IT Equipment.
Equipment to be tested normally has to be disconnected from the mains supply. Equipment
is only disconnected after permission to do so is obtained from the user or a department
manager. This is particularly important in the case of IT equipment and security
Equipment will not be failed because of faulty plug-tops or incorrect fuses. These
will be replaced automatically before testing.
Labeling and Identification.
All appliances and cord-sets are labelled and given a unique I D. This enables us
to track test results over the long term, and make sure that tests are carried out
without fail at the appropriate intervals. In addition, PASS or FAIL labels are affixed
to the tested appliance, with the test date and the re-test date. The labels are
affixed in a position where the user can see at a glance, the status of the equipment.
If required, we can supply labels to your specification.
Certification and Reporting.
All inspection and test results are formally recorded and provided to the customer,
together with relevant certification. Results are normally sent electronically as
PDF files, but can be supplied in printed form, or on CD. The customer also has
an instant inventory of electrical appliances at their premises.
All records are kept on a database. This enables us to inform the customer when re-inspection
and testing become necessary. All inspection and testing are carried out at the customer's
premises. This can be arranged at a time to suit the customer, thus avoiding interruption
These potentially lethal examples were discovered (and rectified!) on recent tests.
Be warned, not all dangers are this obvious.
Although electrically safe, this washing machine was found with the top cover removed
because "it didn't fit under the work top!" The "electrician friend" of the owner
of this guest house had even fitted a plastic strip at the front to make it "safe"
It failed the PAT test of course!
We have always put safety at the top of our priority list, and have always PAT tested
all the equipment we repair for some years now. Since 1999 we have been providing
Pat Testing as a service in its own right.
With more than 30 years experience repairing and servicing electronic and electrical
equipment, we are able to ensure that our customers equipment gets the best possible
treatment, as well as ensuring that they satisfy the law and maintain a safe environment
for their staff and customers.
We test all types of equipment from 230V as found in offices, shops etc, to 115V
as found on building sites, and three-phase equipment as found in factories and

Are you aware that there is a legal responsibility on businesses, shops, clubs, churches
and other places where employees and the public have access, to ensure the safety
of all portable electrical appliances? In the event of an accident as a result of
neglecting to do so, the owner or person responsible could find themselves in serious
