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.
