Depends on the size of the circuit which you did not list.


Is it safe to go from 12-3 wire to a 14-2 wire in the middle of a switch leg?

No. The wire size is dependent on the circuit protection. If the circuit uses a 20 amp breaker you need to run 12 AWG wire on all devices connected to that circuit.

If this question is asking about voltage drop, to size a wire, a voltage is needed.


How do you wire a high watt light to a battery?

Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.


What effect would thinner wire have in a circuit?

The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.


Can you use 10 gauge wire with a 40 Amp circuit 65 feet long?

A #10 copper conductor with an insulation rating of 90 degrees C is rated at 30 amps. A 40 amp circuit would need a #8 wire. To do a voltage drop calculation for a distance of 65 feet, a voltage of the circuit must be stated. Depending on the answer obtained from the calculation you might have to jump up one more size to #6.
