It may be written like and advertisement, but that's because the people who primarily select Square-D believe in their product. (talk) 03:08, 25 February 2009 (UTC)

I'll work on a re-write of this someday; it definitely needs one. Square D is worth a wiki page, but one without the godlike reverence that this brand sometimes gets from electricians, engineers, and facility managers. In any case, it is absolutely untrue that "Square D has an overwhelming market share in the residential market. Most Americans today have a Square D load center in their homes." This may be true in one or two market areas, but definitely not universally true of North America. In my city, Square D product is found in maybe 15% of homes. I like their products and I installed them in my own home, but let's not stretch facts.Yak99 (talk) 03:58, 30 May 2009 (UTC)

Square D is one, if not the only company, named by its customers. The original name was the Detriot Breaker Box Company and was known for the embossed "D" on the cover of the switch box. Soon the contractors would come in requesting the Square D breaker box and the company changed its name. Square D equipment has been used by many, many contractors through the years and is known to have been used in Thomas Edisons lab. It is truly the leader in this arena.

July 2010 Spedy DeletionEdit

This is the basis of a valid article on a significant company. It ma need wikifying but is notable and worthy of an article. Prestonmag (talk) 22:43, 12 July 2010 (UTC)

Yes, this article should stay as Square D is the leading supplier of electrical control panels in the United States. It does need a major rewrite, though. Steelbeard1 (talk) 22:46, 12 July 2010 (UTC)

Manufacturing Dates for Square D QO breakersEdit

In an attempt to clear up when Square D introduced the QO breaker line, I can tell you that my parents' house, built in 1957, originally had a 100-amp split-bus QO panel. So 1955 would be a likely date for their introduction.

The split-bus (offered by most manufacturers) was a much-less-desirable design. When my parents had this panel replaced and the service upgraded, a 150-amp main-breaker QO panel was used. The installing electrician, the late John Gamber of Bel Air, MD, re-used the existing QO breakers since he was convinced of their durability and reliability. All these years later, they perform flawlessly when called upon to trip.

I am a heating contractor now, but we pay attention to what supplies the equipment we install. If we find a Square D or Cutler-Hammer panel, for example, there's no cause for worry. But if we find a Federal Pacific panel, we won't hook up to it, and we advise the customer to have it replaced. —Preceding unsigned comment added by (talk) 19:41, 8 December 2010 (UTC)

Pressure switchesEdit

The square D pressure switch is ubiquitous in farm and similar small-scale water systems in Australia. I have two (one for the bore, the other for the rainwater tank or "house" pump) on my little property at Hobbys Yards. Andrewa (talk) 06:45, 14 June 2016 (UTC)
