Is the intercooler the same thing as an air dryer?? When he measured 106 degrees, what was he measuring in the video?

What about the Champion Centurion over the IR T30?

I would absolutely disagree with the "No ROI" statement. Yes, geothermal costs more due mainly to the cost of the wells. The equipment in general will last much longer than the 12 years stated as well. No equipment sitting outside in the enviroment. Equipment life is in the 20 year range. I...

I would be intersted in that as well...

Hard wire them and the requirement goes away.... A lot of local authorities have amendended the NEC to exempt sump pumps in some cases. All comercial Kitchens, or spaces defined as kitchens have to have be GF now. Try explaining that to the guy that has to depend on the refrigerator and...

:thumbup: Yes I know, but I have had inspectors, the old Authority having juristiction, say they don't care what the definition says.

At least there is no snake in there...

The NEC says that a single device on a circuit has to match the circuit ampacity, IE, A 15 amp dedicated device, 15 amp circuit, 20 amp dedicated device, 20 amp circuit. Multiple devices on a circuit, two or more 15 amp devices and the circuit can be 20. You will get arguments if a duplex is...

No, it does not need a ground. It opens the circuit in the device. It does not ground anything out.

1/0 A is rated at 100 amps for types TW and UF. Everything else is at least 125 amps. You said you have an earth ground in the first post. I assume this is a driven ground rod? If the incoming pluming line is metal in contact with earth for at least 10 ft (IE:not pvc underground), it should be...

If the feeder does not contain a ground, which this one doesn't, the neutral has to be bonded, otherwise there is no low impedance ground path back to the source. This was allowed in all but the latest code revision, which now requires a ground to be pulled, no exceptions anymore. The only...

That is what I would do if you can't push it.

If it has a water service, with metal piping, you can bond to the metal pipe where you can get to it. (assuming the metal piping is continuous with no dielectric unions, bond it once. If not, jumper across any dielectric or non-metal joints) (If the metal pipe is the grounding electrode, must be...

Normal current will not. If the building is metal it should be bonded to the panel, and any metal piping within the building should be bonded to the ground bus in the panel as well, if it is not already. If it isn't, that would be unsafe.

If there are no other "electrically continuous paths" between the two buildings, it is okay. The code used to say that this method was acceptable. Then we started running phone lines, cable lines, etc. The last code revision to the NEC now says you have to pull the ground wire, no option, IIRC...
