About
Landsun Electric Ltd was an electrical contractor in Calgary, Alberta, doing residential and commercial work. The company is no longer trading. This site keeps the name and publishes trade notes instead.
What this is
A journal rather than a business. There is nothing to buy here and no service on offer. What there is, is the practical side of electrical work written out properly: safety procedure, installation decisions, and the working life.
Where it applies
The physics is universal and the regulations are not. Notes here reference Canadian, American and British practice where they differ, but the standard in force where you are working is the one that governs. Where something is jurisdiction-specific we try to say so.
Corrections
Standards move and we will get things wrong. If you spot something out of date, let us know.
