I'm replacing my old timer with a new intermatic T10604R control box. My question deals with the length of the original wires. The new box is larger and I don't think the heater wires that are connected to the 240V lines will be long enough to reach the terminals on the new timer. Will I be able to extend the length of the heater wires with wire nut junctions inside the box, or do I need to rewire the heater so the wires will be the proper length?
