Metal Clad Switchgear Thicker gauge other than 11 gauge

Metal Clad Switchgear Thicker gauge other than 11 gauge

(OP)
Do any of you folks know that any manufacturer can make metal clad 13.8kv switchgear with say 8 gauge metal instead of ANSI 37.2 required minimum 11 gauge?

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

I'd guess there are quite a few, if you have enough money.  If you get past the thickness that they can punch and bend with their normal tools, it's going to get costly.   

A Google search for metal-clad switchgear should turn up a lot of independent "tin-benders" who buy breaker kits from the major breaker manufacturers and  build their own gear.

I'd check with maybe PowerCon, Controlled Power, Lakeshore as a start.  I'm sure there are many more.

Thanks for info!  I know Controlled Power and have bought equipment from them before.  They have never done it.  Some engineer put this in our swichgear specs.  I will probably stick with 11 gauge.

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

Also check with Russelectric and similar custom switchgear mfrs. With time and money almost anything is possible.

And then there is ASCO...but it is going to get expensive as you probably already know.

In Chicago there is GE Zenith Controls.  They do just about anything.

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

We can do that.  

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

Why would you want to use 8 gauge? It is very hard to work with when building gear.  

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

Zogzog: We have problems with 11 gauge cubicles twisting and the roll-in breakers don't make contact properly in the receptacles.  I could send you some info to give me some ball park estimate.

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

Twisting? This gear mounted on a fault line in Cali or something?

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

(OP)
Twisted during the transportation or deforming because the floor may not be leveled.  It is floor mounted in a room in Northern VA areas.

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

I am sure it is just a matter of some adjustments to your gear, that would be the first thing to look at. Custom gear with 8 gauge steel will cost 2x or 3x what you paid for yours.  

RE: Metal Clad Switchgear Thicker gauge other than 11 gauge

Typical switchgear is a bolted frame construction. For the most part, a heaver gauge material will not prevent twisting. Gear must be level and square for drawout breakers to opperate properly.
Proper installation is everything. An option is to order switchgear with a seismic rating. Manufacturers typically add gussets & stiffeners to gear to obtain the seismic rating. This will help to assure that squareness is maintained. In the end though...Good Installation.

We are an OEM of MV switchgear and can provide 8 ga. construction. We would need plans and specs etc. You can see our capabilities on www.gavangraham.com
