What type of electrical installation is not covered by BS 7671?
Systems for distribution of electricity (supplier's transformers, substations, etc.) Equipment of motor vehicles (except caravans, mobile units) Equipment on board ships Equipment on board aircraft Equipment of fixed and offshore installations (oil rigs, etc.) Mines and quarries Lightening protection systems Radio interference supression equipment Electrical equipment of machines
Where in the National Electrical Code book does it state that it is the true minimum permitted for electrical installations?
NEC 2005 Article 90.4 - "This code is intended to be suitable for mandatory application by governmental bodies that exercise legal jurisdicition over electrical installations, including signaling and communications systems, and for use by insurance inspectors. The authority having jurisdiction for enforcement of the code has the responsibility for making interpretations of the rules, for deciding on the approval of equipment and materials, and for granting the special permission contemplated in a number of the rules."
What are the hazards associated with carrying out scheduled maintenance tasks on electrical equipment and how can they be minimised?
The main hazards are being electrocuted and falling off a ladder. They can be minimised by training, which is why the work is done by electricians, who in addition are familiar with the electrical regulations in the area where they live.
To prevent accidental electrical shock most electrical equipment is?
Grounded.
What is more complicated tool that may refer to a small electrical appliance?
trancestor
What are the ROHS regulations about?
ROHS, or the full name, The Restriction of the use of certain Hazardous Substances in Electrical and Electronic Equipment Regulations is restrictions on the presence of certain hazardous substances in new electrical and electronic equipment.
What type of installations?
There are various types of installations, including software installations on computers or devices, physical installations like machinery or equipment in a manufacturing facility, and infrastructure installations such as electrical wiring or plumbing in buildings. Each type of installation requires specific expertise and procedures to ensure proper setup and functionality.
Define earth voltage and neutral voltage?
As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground.
Is there uranium in X-ray machines?
No, X rays are EM radiation and are produced by electrical/electronic equipment

what is lugs earthing?
Lugs earthing, also known as lug grounding, is a crucial aspect of electrical systems that ensures the safety of both people and equipment. It involves the use of electrical lugs or connectors to establish a secure and low-resistance connection between electrical equipment or conductors and the earth (ground). This connection serves several essential purposes in electrical installations:
Does electrical design require a license?
The E&A Regulation Act requires professional electrical engineers to design electrical installations on all non-exempt projects. Master electricians licensed by the State Electrical Board are authorized to plan, layout or supervise the installation of wiring, apparatus, or equipment for projects they are installing.
Electrical safety test should be carried out whenever electrical equipment is commissioned?
Test and inspection of electrical equipment should always be carried out when commissioning . This will done before voltage is applied , usually known as dead testing to verify the suitability . Live testing will then be carried out to confirm compliance with regulations .
What is the national electric code?
The National Electrical Code is the recognised standard to which all electrical wiring and installations must adhere to. It is a requirement of selling a house that all wiring and equipment must feature this code to prove it has been correctly fitted.
Where can I find some electronic enclosures in New York?
There are several electronic equipment stores that may sell electronic enclosures. Stores like home depot may also sell electronic enclosures.
Is wiring of an automobile or aircraft covered by the Philippine electrical code?
These types of vehicles will have their own regulations as to their wiring, as governed by the manufacturer of the equipment. The building that the vehicles are stored in will be under the electrical code mandate.
