Dear Clayart electric folks:
Oh yes I do want to check the voltage at the panel.
How do you check the voltage at the panel. I suspect I'm getting only 200
volts, instead of 220, and want to check this before I takethe kiln in for
a checkup.

Hi Lili,
THe simple answer is the cost in Watts will be :
Voltage drop times the amps your kiln is drawing.
IF your kiln is on High, and it draws 48 Amps:
1 volt drop = 48 watts
2 volts 96 watts
...
You can check this experimentally by reading the voltage at the panel and
then read the voltage at your kiln when it is running.
( YOu probably don't want to do this.)''''

Actually if you are only interested in the voltage drop in the wiring the
easy way to measure it is at the kiln, You do not have to go to the service
entrance meter panel.
Just measure the voltage at the kiln with the kiln turned off. Then turn it
on and you will see the drop and can measure it.
At no load there is no voltage drop and you can see if the power company is
giving you full voltage. If you do this test at the meter you can see if
the power company needs to put in bigger wire from their transformer to
your meter panel.
If this measuring scares you get an electrician to do it for you.

Hi John
TO Actually check at the panel, you would take off the 6 screws covering the panel, and put the probes of your Voltmeter on the two lugs where the voltage comes into the panel. YOu can get a cheap voltmeter at radio shack for $10.00, or a pretty nice one at sears, home depot, etc for about $100.00.
Please be carefull taking off the cover to avoid knocking off
any breakers. Generally they snap onto the back bus bars. sometimes you have to wiggle the cover a bit to get it off.
Another option: You can check the voltage at your dryer outlet (if it is a electric dryer) and you will have almost the same reading, without the bother of taking off the panel cover. As long as there is no load on the circuit, there is virtually no voltage drop. Just stick the probes into the two hot slots.
