Human Factors
The aircraft was operating without an APU due to MEL. Ground power and air was requested on the in range call.  Upon arrival at our gate the left engine was shutdown and the hand single was given to the ground lead for ground power.  The individual acknowledged with a nod.  During this time the aircraft beacon was on.  After several minutes waiting for ground power I noticed on the ICAS that the fueler had hooked up to the aircraft.  I immediately shut down the aircraft and went to emergency power.  I went out to speak with the supervisor in charge of training the new ground personnel at IAD.  I explained the importance of stopping an unsafe action and keeping personnel clear of the number 2 engine.  Further; I explained how dangerous it was to attempt to fuel an aircraft while an engine is running and with passengers on the aircraft.  I was disappointed with the response that they are new and by placing the blame on the fueler.  This incident was a total breakdown in the safety chain.  The ramp personnel failed to stop or acknowledge a major safety issue.  Clearly some basic training is warranted.  I would also question why we have personnel on the ramp whom are not receiving the proper training.  Under no circumstances is this acceptable and the new ramp personal need to focus on safety and be taught correct procedures.  If you see a safety issue; say something and attempt to correct it.
CRJ-700 Captain reported ground personnel failed to follow SOP and hooked up to fuel when an engine was still running.
