An electrical apparatus is provided that has an electrical device encapsulated in a plastic encasement. The encasement includes an inner shell and an outer shell. The inner shell has a thickness greater than the outer shell and the inner shell is more flexible than the outer shell. The inner shell is formed from a first resin composition that, when cured, has a tensile elongation at break of greater than 5% and the outer shell is formed from a second resin composition that, when cured, has a tensile elongation at break of less than 5%.
