The Pros and Cons of 347 V for Lighting in Buildings


The BC Chapter of the The Illuminating Engineering Society is hosting an information session on “The Pros and Cons of 347 V for Lighting in Buildings” on September 24, 2013.

Since 347 V is not used in the US, the question arises whether the 347 V for lighting in Canadian buildings is still an appropriate choice or a review of the usefulness of the 347 V system is warranted with an aim to harmonizing with common standards used South of the border.

The 600Y/347 V AC, Three Phase, Four Wire System has 347 V to neutral, and 600 V between any two phases. It is the most common electrical service used in new medium to large size commercial buildings in Canada. The 347 V Single Phase is often used for interior lighting.

We would like to address the advantages and disadvantages of 347 V for lighting in buildings in a panel discussion and would like to invite you to participate in this event as well as contribute to the discussion.

WHEN:   Tuesday, September 24, 2013  *  5:00 PM – 8:00 PM

WHERE: The Arbutus Club  *  2001 Nanton Avenue  *  Vancouver, BC
