Yup, it's the world's cheapest T-Switch here, but would you use it?

...would you use it?


Do you mean with or without PPE?

I was not aware that you could clamp sealtight with a NM connector, and I have been buying the expensive ones all along.... BTW what are the two wires exiting the panel on the bottom left, ground wire?

I have seen these SqD devices and played with them. FWIW, I'm kinda surprised at SqD for offering such a product for isolating generator current from POCO current - it just seems kinda cheesy to me. [Linked Image] My personal choice would be a double-throw, center-off safety switch (along with properly fitted connectors to the box, of course).

This isn't my work fellas,
but that $.02 T-switch would most certianly beat my quotes.

West-Southern Inner-Northeast ...
This type of pictured circuit-beaker “intelock” is sometimes found in RVs to select between an on-board genset and “shore power.” I am not sure many electric utilities have caught on to this potential death trap. What amazes me is the 2-pole breaker across from a 1-pole breaker—backfeed guaranteed, unless only one pole of the 2-pole breaker is used. On its best day that can’t work without significant hazard to life and property—unless this is a 100% “off-grid” system.

{The white left enclosure looks like a Trace inverter accessory—the installation may be for a photovoltaic home-power installation.}

OK how do you guys feel about this one, (maybe someone can enlarge it)

Reliance Controls

I was thinking about using this in my own house, the mechanism is not flimsy but it removes with the cover.

For the average DIYer this could be a problem.

Bob,

Here's a 2x version, anything past that gets really distorted.

[Linked Image]

I REALLY don't like the idea of it coming off with the cover.

i concere with the group here, but lack the verbage to convey the sentiment other than 'cheesy'

Bjarney (et all) could you please elaborate??

Sparky:
I guess the thing I don't like about it is that the little "either/or" arm (for lack of a better description) looks very flimsy - as a matter of fact, when I was "playing" with one (not installed) I found it rather easy to bend the arm out, allowing both breakers to be closed (not good [Linked Image] ). I hope the one I was handling was the exception and not the rule.
