I'm sure your electrician knows what 3 wire is. I assume he licensed in your area and knows the local codes. I wouldn't worry about all this banter and reading a bunch on wiring unless you want to tackle it yourself. Let the guy or gal do the job and anything you don't understand I imagine they would be happy to explain.
