Wire gauge required for 30 amp heater?
A #10 copper wire with an insulation rating of 90 degree C is rated at 30 amps. If the heaters exact draw is 30 amps then go to the next wire size. That will be a #8 copper wire with an insulation rating of 90 degree C and it is rated for 45 amps.
Does a 1993 Mercury Topaz have a relay switch for the air conditioner and heater?

Adding a 240 volt 20amp electric heater in my crawl space Would like to use my 20 amp circuit for outside condenser Both would never be on at the same time Do they make a switch for this?
Yes, what you are looking for is a double pole double throw switch. The center lugs are connected to the incoming line. Then the top lugs could be connected to the electric heater and the bottom lugs connected to the condenser. The trouble lies in finding a switch with a rating of 20 amps. These types of switches are usually used with a stand-by generator and rated at 100A and greater. Think I remember seeing one at 60A once. You might want to think of using a DPDT relay rated at 30A with a 120 volt coil. With a switch to operate it the relay. Depends in what part of the country you live, long winters switch off for heater, long summers switch off for conderser.
Functional difference between a motor and a relay neuron?
Motor neurons are the efferent neuron which carry impulses from CNS to muscles while relay neurons also known as Inter neurons connect both afferent and efferent neurons.
Can you use a 50 amp automotive relay with a 12V dc coil to control 12V ac 500 watt halogen lighting?
No, you cannot use a 50 amp automotive relay with a 12V DC coil to control 12V AC 500 watt halogen lighting. Automotive relays are designed to work with DC power, not AC power. Additionally, the amp rating of the relay refers to its capacity for DC load, not AC load. You should use a relay specifically designed for AC applications with the appropriate voltage and current ratings.
How to Wire a low voltage thermostat for a 220v baseboard heater?
You will need a relay with a low-voltage coil and 220v contacts rated for the current load of the baseboard heater. If you have a low-voltage transformer, see what its output is rated at (typically 24 volts or less). Then go to an electronics parts store or call some place like Digikey (phone 800-344-4539) and tell them you need (for example) a double-pole single-throw normally-open relay with a 24 volt coil and contacts rated at 30 amps at 240 volts (change these numbers to match your situation). If you do not already have a low-voltage transformer the parts store call sell you one to match the relay coil voltage (be sure to specify if you are connecting the transformer input to 120 volts or 240 volts). Then wire it up as follows: connect the transformer output (24 volts in the example above) in series with the thermostat contacts and the relay coil. Connect the 240 volt supply to the moving arms on the relay, and connect the contacts the arms touch when the relay operates to your heater. Now when the temperature drops below its setting the thermostat contacts will close and connect the relay coil to the 24 volts, the relay will operate, and the 240 volts will be connected to the heater. When the temperature rises above the thermostat's setting, its contacts open, the relay contacts open, and the heater is disconnected. Depending on where you live there may also need to be circuit breakers, protective ground wires, etc.--ask an electrician.
