Thanks for that reply I am still not familiar with the term -- combo UPS/line conditioner What is this precisely, I guess since we don't normally experience such thunderstorms very often , here in the uk, we are less familiar with this requirement. Here in the uk we have stable good quality electricity supplies.Our national grid never blips at all. But no national grid can cope with massive thunder storms. In the news today , it was reported that 15 houses were struck with lightening and set on fire which required every fire appliance for 50 miles around to deal with them. All available emergency services were out on call dealing with fires and injuries.It really did catch everyone out. However it's not normally a regular occurance , of course we get regular thunder and lightening but not like last night. John >>John Richard Smith >>[EMAIL PROTECTED] >> >>
