    In the selection of dry type transformers, how do I go about determining the proper rating of the transformer circuits?

    Rating Of Transformer Circuits

    There are some subjects in the CE Code that often become a source of heated discussions by the users. Selection of dry type transformers and selection of a proper rating of the transformers circuits is one of these controversial subjects.

    So, let’s try to clarify this seemingly complex issue. First of all - we need to refresh the understanding of a circuit rating in accordance with Rule 8-104. This rule states that the rating of a circuit or a feeder is the ampere rating of the overcurrent device protecting the circuit or the ampacity of the circuit conductors, whichever is less. This rule also states that the calculated load in a circuit shall not exceed the ampere rating of the circuit (i.e. shall not exceed the rating of the circuit O/C device and the ampacity of the circuit conductors).

    Will CSA Z462 be adopted into law by Provinces & Territories?

    NO, CSA Z462 will not be law in Canada. CSA Z462 will be a consensus based CSA Standard, that may also be a National Standard of Canada (pending the Standard Council of Canada approval). Each Province & Territory has the latitude to reference or adopt CSA Z462 in whole or part into law. Even if CSA Z462 is not adopted into law it will only be a consensus based Standard and industry accepted best practice.

    Will layering of ATPV rated clothing achieve a higher ATPV rating and how does it affect the Total System Arc Rating?

    PPE And Layering...Total System Arc Rating

    Let’s discuss electrical specific Personal Protective Equipment (PPE) for arc flash protection. This article will talk about what layering means to your personal protection. We’re talking about the cal/cm2 rating of protective clothing, and its Arc Thermal Performance Value (ATPV).

    As a subcontractor, what do I need to know about Subcontractor Default Insurance?

    Subcontractor Default Insurance... The Subcontractor’s Perspective

    The last ten years have seen the increasing emergence of Subcontractor Default Insurance, which has been marketed as an alternative to the conventional bonding approach. Subcontractor Default Insurance, or Subguard®, the trade name used by Zurich North America for its Subcontractor Default Insurance, has become fairly common on larger construction projects, and subcontractors must be aware of its potential effect on them and on the project.
