RE:	Island Park/Shreveport, Louisiana
	Electrical Drawings

Dear Jim,

Article 230.70 of the 2005 National Electrical Code says – Means shall be provided to disconnect all conductors in a building from the service entrance conductors.

Article 230.2 Number of Services – One Building can have only one service unless permitted in 230.2 (A thru D).

	Article 230.2-A – Covers fire pumps, emergency systems, etc.

Article 230.2-B – Covers (1) multiple occupancy buildings with no available space for the service equipment of one service and (2) a single building sufficiently large to make two services necessary.

Article 230.2-C – Covers service in (1) excess of 2,000 amperes, (2) has to do with single phase services (3) by special permission.
	
Article 230.2-D – Covers need for different voltages.

Article 230.2 – C, (3) above covers this situation where the local authority allows them to do so.

In the future, we need to include in the specifications that if the contractor makes drastic changes in the installation that do not reflect that shown on the drawings, he must have advance approval from the engineer, and that he will pay to have the drawings changed to reflect what is installed.

After speaking with you today, we need to add a note to the drawings that if the local power company doesn’t provide the service from their transformer to the main disconnect, the contractor will include this work in his bid price.

Sincerely,

Emmet G. (Pete) Dammon, P.E.
