Looks you have done it but......go to Home Depot, Lowes, etc and see what they have in whole house surge protectors for your main line coming into the house. Hire a certified and competent electrician to install. Get several quotes before installing. Make sure everything is in writing -too many fly-by nights improvement people out there that install wrong, illegal, or just hazardous (not up to code) jobs to yourself and to your house.
