Wrexham striker Brett Ormerod grabbed two of the goals as his side cruised to victory over Blue Square Bet Premier strugglers AFC Telford United.
Ormerod pounced after just two minutes, stabbing home a rebound.
Wrexham scored three times in 11 minutes, Nick Rushton fired in through a crowd and Danny Wright finished from a pass from Ormerod, who then converted Johnny Hunt's cross for his second.
Substitute Jake Reid headed in a consolation goal for Telford.
Wrexham stay third, four points behind leaders Grimsby Town with a game in hand, while Telford, who have won just once in 12 games, have now plunged to 20th, just a point away from danger.
Telford are due to host Wrexham in the return at the Bucks Head on New Year's Day (12:00 GMT).
But first they travel to fellow strugglers Stockport on Saturday, while Wrexham host lowly Tamworth.
VIEW FROM THE DRESSING ROOM
Wrexham manager Andy Morrell told BBC Radio Wales:
"I thought we were worthy winners and did enough to win the game.
"It was a tight first half and I thought the second goal was crucial, but once we got that I thought we were good.
"It's just annoying that, once again, we concede a stupid goal."
