Electric Heat Strip Question

[building in central pa]

In the carrier suplemental electric heat data they list the KW for each heater at 240V and 208V. For example a KFCEH2901N09 is 9 KW at 240V but only 6.8 KW at 208V. This may be a dumb question, but which number is the heater actually going to put out? Do you use the 208V value or the 240V value???

If it's for your home, it should be 240V. The 208V is for 3-phase power which is rarely used in homes.

The majority of resi in PA is 240.

But you will find alot of 208/230 volt single and three phase in commercial.

If you really want to get the correct number...
measure the voltage you are going to use.

One house might have 219 volts.
The house next door might have 248 volt.

Residential is figured @ 240 V, single phase or 9 KW
