Rocky Mountain Power crews were scrambling Tuesday to restore electrical service — and thus air conditioning — to almost 4,000 homes affected by scattered northern Utah outages before daytime temperatures soared once more toward triple digits.

The outages, causes intially unknown, hit 3,380 customers in the 84015 zip code area, roughly Clearfield and West Point, as well as some 600 homes in the 84123 zip code area of Taylorsville.

All services were restored by late Tuesday morning to the 84015 outages, where a faulty circuit breaker was repaired. However, about 600 homes in the 84123 district remained without power late Tuesday afternoon.

Rocky Mountain Power spokesman Dave Eskelsen said a broken underground cable was the problem in the Taylorsville outage, and that was taking longer for crews to address.
