Joe-

For the discussion group:

Now this is one I've never seen before. A CATV power unit with a gas line
connected! I'm assuming that there is some sort of engine or thermocouple
device in the cabinet that provides stand-by power to the CATV system.
Perhaps in this area there are extended power outages that require more time
than batteries would provide. Extra funny if you consider that I found this
box almost within walking distance of Hoover Dam, Boulder, NV! Anybody know
what sort of power device is in the cabinet?

Bob

Natural gas powered generator set. Used in place of battery banks in areas with unreliable electrical power.

Wouldn't 250-104 (3) x(b) [NEC 1999] apply here. I don't see a ground/bonding clamp.

that is a very good idea, but i see there is no earth bonding between the gas supply andd the CATV cabinate,
also were is the physical protection to the gas meter, surely this is required ???

I believe the yellow bollards are intended for physical protection.

Kohler [and likely others] makes a nice 48VDC 'COM-6' genset series for backup of telecomm ["SLC-96"] subscriber-carrier huts in more remote areas.

Georgia Power has these things all over Atlanta, but usually larger. They are called "peakers". On high demand days these kick on to make up the diference to avoid brown outs. I don't see anything here to indicate that this is CATV, but I'll take your word for it. I guess the cable company wants to insure reliability if the power goes out.

Ummm I have a silly question.

If the power goes out, how are you supposed to watch cable television?

its not a silly question, but is a funny one i had quite a chuckle over that one,

but seriously, how are you sopposed to watch TV with a power outage.

The only thing i can suggest is as we knoe the CATV companies will ensure there programs can be watched, why dont we get ourselves some gas gensets for our residences then.

> If the power goes out, how are you supposed to watch cable television?

We can't watch TV but the cable company has two main reason for the genset:

To feed any downstream customers/equipment that do have power.

To keep the temperature right if it is a controlled environment enclosure. Some of the electronics in these units can not withstand extreme cold and heat.

Cable's not just for TV anymore!
I use a cable modem for the computer and if I had a good enough UPS or a laptop computer, I could surf the net or even watch TV on the computer without power.
