No injuries were at the evacuated hotel just off northbound Route 17.
The explosion occurred in a basement electrical panel at the rear loading area just after 7 a.m., instantly drawing firefighters from Hackensack, Hasbrouck Heights, Little Ferry, Moonachie South Hackensack and Wood-Ridge, responders said.
Firefighters doused the blaze, evacuated the hotel, searched for possible victims, then ventilated the building. Guests were allowed to return about two hours after firefighters arrived.
The Moonachie First Aid & Rescue Squad was also among the responders to the three-alarm call, as was PSE&G.
