The Georgia Power Co  whole-house plan is called Premium Protection, and I 
believe is being sold by power companies all over the USA. They do the magic on 
the electric lines, CATV, and telephone lines-- all where they enter the house. 
They do provide a warranty ("insurance"?) against losses to most household 
appliances and electronic equipment.
     The Internet web site says it does not cover "unusual electronic 
equipment" and even the supervisors at the call center could not tell me if ham 
gear would be covered. I asked them to send me the actual "insurance 
policy/warranty form" and they mailed it today. As soon as I get it I'll report 
here. Also I'm polling the S.E. DX Club members to see if any of them have any 
experience with this program.
      I know that some of the major homeowners insurance companies cover you 
for lightning strikes-- but probably not normal surges.

     My office building (abt 35 years old) in the past had big problems with 
just normal surges that would blow power supplies on computers and telephone 
equipment. The power company put a recording device on the line in my office 
and you could see spikes occasionally where the 120 volt line would jump up way 
higher for an instant. They put some device in the building (a surge 
suppressor?) and that solved the problem.

###  go to the joslyn link below...... then  click on the  surgitron 1    
series of protector's.    

##  Ok.. then scroll  to bottom of page..where the various pdf's  are 
located... and  find the pdf marked  " 1265-85M/MN"     this is the common  
"single phase, 3 wire "  variety.    The M version  is used on main panels that 
have the neutral and grnd bonded together.    The MN  version  is  for  sub 
panels and any downstream protection, and also includes N-G  protection.    
Both these versions  include back up modules in case the primary protection 
blows the internal fuses.   It will handle  1000 x 20KA hits..and comes with a 
5 year warranty.  [ It will take  12,000 x 10kA hits..and  400,000  x 3 KA 
hits].   You can even get options like SS cabinet  or even an 'event counter'   
Max  single pulse rating is 320KA . 

##  shipping weight on this arrestor is 11 kg.   This and the  208/120 v 3 
phase version..and all other versions in this series are the NA standard for 
all telco's  across the usa and canada.   This  surgitron 1 series of 
protection has been in continuous use  for decades now.   It's an industry 
standard  for not only telcos',  but most commercial buildings as well.   The 
240/120 v  single phase unit is easy to install near your main 200A panel..and 
will never let you down.  It's easily the ultimate 'real deal' protector  for 
any home. 

##  if u look at pdf   " 1455-45-80-85 iom "     you will see a more detailed 
write up.  1M  of wire is 1 the protection has to be very close to the 
panel....otherwise u will get an additional  300v let through on a  typ 10 KA 
surge.    These 3 phase  208/120 v units  are designed for panels that have the 
neutral of the 23 phase Y  bonded to grnd.    They also offer  protection as 
follows  L-N   L-G   and N-G.    They also use a combo of even more movs  + gas 
discharge tubes  between  N=G.... even though the   N is bonded to the grnd  in 
the main panel.  

##  Their JSP series of protection is also superb..... just don't order the 
optional EMI/RFI filter.    They can't be used with any kind of 'pulse train'  
power  supplies.... IE:    any kind of switching supply  or typ ham radio HV B+ 
supplies..which are also the original pulse train supplies.  IE:  typ B+ supply 
in a ham amp..under load... sucks a huge amount of peak current every 8.3 
msecs....  for aprx 2 msecs in duration. 

later....... Jim   VE7RF
