Why the name Just A Phase?

Our unique name derives from the saying 'It's Just A Phase'. A Phase is not just a period or stage in a series of events but it can also be associated with Electricity - In an A.C Circuit current flows in both directions. The Phase Acts as a main supply line whilst the neutral acts like a return path for the circuit to be completed.
