Article evaluation
Article used: Environmental science

Evaluating Content
Most of the article stayed on topic, but the final section Regulations driving the studies seems out of place and does not add anything to help understand the topic of environmental science. While also being off topic, it only mentions two different regulations; maybe adding more regulations, and more recent ones at that, would make this section more relevant or it should belong on its own page. Something that was distracting in the article were the images used throughout the article.The article just uses nice pictures of Earth and some coral, whereas maybe charts showing data concerning global warming or pollution would be more appropriate.

Like I mentioned before, the final section concerning regulations is a bit out of date, seeing as how it only includes two regulations with one from 1969 and the other from 1996. There have been many more regulations put into place since then and one of the regulations has even had major amendments since it was first signed into law.

I do not think that anything else needs improvement in this article.

Evaluating Tone
This article is very neutral on the subject, but it does only show what the US defines as environmental sciences. The article only describes the basics of environmental sciences and does not appear to be heavily biased towards any one subject.

The article does not go into any detail on some of the other things mentioned in the "Terminology" section such as mathematical modeling.

Evaluating Sources
After checking a few of the sources, it seems that the links work fine and the sources support what was stated in the article.

Each fact is referenced with an appropriate, reliable reference. The information comes from a bibliography, a university and government cites. Each of theses sources are reliable and neutral.

Checking the talk page
On the talk page,there are multiple conversations about how poorly the article was written and how it was too political back in 2005 and 2007. Most of the talk page is about how the article needed to be rewritten.

The article is rated as C-class and is part of 3 WikiProjects.

Article: Electric Switchboard

= Electric Switchboard = An electric switchboard is a device that directs electricity from one or more sources of supply to several smaller regions of usage. It is an assembly of one or more panels, each of which contains switches that allow electricity to be redirected.

Enclosure
Modern industrial switchboards are metal enclosed and of "dead front" construction; no energized parts are accessible when the covers and panels are closed. Previously, open switchboards were made with switches and other devices were mounted on panels made of slate, granite, or ebony asbestos board. The metal enclosure of the switchboard is bonded to earth ground for protection of personnel. Large switchboards may be free-standing floor-mounted enclosures with provision for incoming connections at either the top or bottom of the enclosure. A switchboard may have incoming bus bars or bus duct for the source connection, and also for large circuits fed from the board. A switchboard may include a metering or control compartment separated from the power distribution conductors.

PLANS FOR ARTICLE

 * Section for different types of switchboards (either entirely new section or edit Enclosures)
 * Add section for electrical switchboard U.S. standards

Edited Article
= Electric Switchboard = An electric switchboard is a device that directs electricity from one or more sources of supply to several smaller regions of usage. It is an assembly of one or more panels, each of which contains switches that allow electricity to be redirected. A switchboard is divided into different interconnected sections, generally consisting of a main section and a distribution section. These two sections are sometimes replaced by a combination section, which is a section that can fulfill the roles of both aforementioned sections. Switchboards can also sometimes come with an auxiliary section that is used to house devices that cannot be housed in the same section as other devices

Definition
The U.S. National Electrical Code (NEC) defines a switchboard as "a large single panel, frame, or assembly of panels on which are mounted, on the face, back, or both, switches, over-current and other protective devices, buses, and usually instruments". The role of a switchboard is to allow the division of the current supplied to the switchboard into smaller currents for further distribution and to provide switching, current protection and (possibly) metering for those various currents. In general, switchboards may distribute power to transformers, panelboards, control equipment, and, ultimately, to individual system loads.

Components
Inside a switchboard there will be one or more busbars. These are flat strips of copper or aluminum, to which the switchgear is connected. Busbars carry large currents through the switchboard, and are supported by insulators. Bare busbars are common, but many types are now manufactured with an insulating cover on the bars, leaving only connection points exposed.

The operator is protected from electrocution by safety switches and fuses. There may also be controls for the supply of electricity to the switchboard, coming from a generator or bank of electrical generators, especially frequency control of AC power and load sharing controls, plus gauges showing frequency and perhaps a synchroscope. The amount of power going into a switchboard must always substantially equal the power going out to the loads ( less the losses in internal conductors and consumption by internal devices such as pilot lamps, space heaters, or others).

Enclosure
Modern industrial switchboards are metal enclosed and of "dead front" construction; no energized parts are accessible when the covers and panels are closed. Previously, open switchboards were made with switches and other devices were mounted on panels made of slate, granite, or ebony asbestos board. The metal enclosure of the switchboard is bonded to earth ground for protection of personnel. Large switchboards may be free-standing floor-mounted enclosures with provision for incoming connections at either the top or bottom of the enclosure. A switchboard may have incoming bus bars or bus duct for the source connection, and also for large circuits fed from the board. A switchboard may include a metering or control compartment separated from the power distribution conductors.

Standards
In the United States, standards and regulations for electrical switchboards are managed by several organizations. The National Electrical Manufactures Association (NEMA) is a trade association which also publishes standards for the construction and application of electrical switchboards that manufactures produce. The National Electrical Code (NEC) sets standards for the installation of electrical wiring and equipment, including switchboards. The Occupational Safety and Health Administration (OSHA) has also set electrical standards for safety which includes standards for the installation of switchboards.

Assignment 9 completed
After reading my peer review I added more citations and references as the review suggested. I have also added a new section on standards since my reviewer suggested that I should add more sections. Although the suggestions didn't specify which sections could use more information I did find the suggestion on adding more sections to be helpful.
