I am searching for wiring details for using Aluminum Housed Wirewound Power 
Resistors used for thermal control inside an insulated housing for the 
seismic sensors.  It has been suggested wiring several such resistors in 
series to accomplish a 10-30 watts from the 110v AC house supply source. 
I'm a little leery about the house current for safety reasons and possible 
AC hum.

In studying the Mouser Electronics catalog, I can find several possible 
configurations using one to several resistors in series.  The resistors 
specify their wattage capability, but have different resistance values to 
choose from.

If anyone has done this and has specific values etc., I'd appreciate hearing 
from you.

Light bulbs attract bugs and other unwanted critters!

Thank you,
