Umbrella insurance for rental property with fuses?

[David C.]

Does anyone know of an insurance company that will offer an umbrella policy for a 3-family rental property that has fuse boxes? I have a homeowners policy with a company but liability is small and they don't offer umbrellas so looking to have the extra coverage. Property is in an LLC but the property also represents 80% of my wealth so want to protect it just in case something ever happens.
