Of all the DIY trades that exist, it is easy to believe that electrics is one of the most dangerous, if only for high voltages and possible explosions in the case of such mishaps as incorrect wiring. It is little wonder that people often turn to professional electricians rather than attempt to do electricians work themselves if it is something more challenging than just changing a light bulb or replacing a fuse. Of course, given that you are the customer, and as long as you are in a position to pay for a service that is up to code, you can have anything you want. You are the boss. This is both a privilege and a responsibility; try not to be too brief when it comes to outlining the task at hand.
The demand for professionalism can and does start before there is the first contact between professional person and customer. Sometimes it is just a matter of not being careless with tools, or taking the initiative to buy new ones in advance, if only to avert delays with service provision.
What are the qualities of a “good” electrician? Apart from a good knowledge of electrics, important ones are good analytical skills and hand eye co-ordination, patience, a good sense of balance and physical fitness.
You should make sure, especially if the project is a serious one, that an electrician is registered. And bonded: a bond being an insurance policy for which the contractor pays a premium; which forms the basis of a guarantee.
Some electricians cannot resist the prospect of being paid as soon as possible. But if an electrician demands money before starting work, the rate should not be more than 10% of the cost of the project, evaluated in advance.
