Rjemote Power Distribution Panel

[EEJaime]

Hello all,

I have an application where I need to get power out to a remote area of the site. Many years ago, I specified a piece of equipment that suited this situation perfectly. I no longer have the name of the manufacturer I specified and those documents are with a former employer and probably no longer exist. In any case, this switchgear manufacturer made many items, but one of them consisted of a 480V incoming main circuit breaker feeding a 480V distribution board which in turn fed a 480-208Y/120V,3Ph,4W Transformer, I believe up to 75 kVA and then a 208Y/120V, 3Ph,4W branch circuit panel with MCB. All of this was housed in a single, stand up, weatherproof switchboard section. I believe the manufacture was in the northeast US, I am in Caliornia.

This sound familiar to anyone out there. I am sure many custom houses can make it, I just was very happy with the quality, flexibility and follow through of this manufacturer.

If I can't track it down, I'll detail it and let the contractors figure it out, but I always like to have a source for anything I specify.

Thank you in advance, have a good day,
EEJaime

We have used the Cutler Hammer Mini-Power Center.

My Google search turned up the Canadian website, but I assume they are still available here in the States:

These have been around for a long time. Formerly a Westinghouse product.

dpc,

I've used those many times but they have limited size and configurations. I was able to contact my previous employer and dug up the following manufactur's link. It is very useful. I highly recommend this equipment for those remote locations, we've used them for stadium outbuildings, school maintenance and concessions, remote restroom buildings,etc..., their big advantage over the Eaton unit or Square D's MiniPowerZone units is that you can feed both 480V and 208/120 V loads.

they call them Unitized Distribution Substations.

Thank you for your help.

Yeah, the Eaton "Mini Power Center" product concept is available from all of the major players; Siemens calls them "Sentron Power Centers", Sq. D calls them "Mini Power Zones", GE calls them "Servicenter". But they are limited to about 30kVA and on the 480V side it's only the Main to feed the transformer primary, no other 480V distribution. That other one looks nice if you want both.

You could also just specify an Outdoor Switchboard with a main, a few 480V feeders, and a small transformer feeding a "Lighting Panel". All the Swbd mfrs offer that as standard options.
