Flight Attendant 4 boarded and almost immediately smelled a burning electrical smell; when Flight Attendants 1;2;3 came aboard they confirmed smell and we notified First Officer who confirmed he smelled it too and went down to tarmac to check unit. Captain also smelled and called Maintenance. We were advised to leave aircraft and wait on jet bridge.  Name came and confirmed she smelled it too; she contacted Operations and they advised us to go to [the] clinic; after we asked several times; if they would be able to do the necessary tests for fume events; they reassured us it was the right place to go. we were unsuccessful in reaching [the] SAFETY line till after we had been at clinic for more than an hour already. SAFETY advised us we needed to go to ER not clinic. We then took a ride to ER. The First Officer was professional and helpful; the Captain unprofessionally dismissed us. Fume events need to be taken seriously and all stations and bases should have strict protocols on hand to deal with them. They need to be aware of where to send crews for correct testing as it is time sensitive.
Flight Attendant crew reported a fume event during preflight at the gate resulting in physiological symptoms.
