How do you run electrical wiring on the outside of a house?
The Proper Way to Run Wiring on the Exterior Wall of a House There are two ways to run electrical wiring on the exterior walls of a house or other structure.

Does 220 wire need to be in conduit?
No, there's no such restriction. If your circuit requires a neutral it must be run with the hot wires (conduit or in cable), similarly with the ground. However, if you don't need the neutral, you don't need to run it ( conduit or not).
How to secure cable to wall?
Secure the cable to the wall, using cable staples or cable straps. Place a staple or strap within 12 inches of each box and at intervals not exceeding 4 1/2 feet between those two staples or straps.

How to determine the size of a conductor?
Plan your installation. The size of the conductors is primarily determined from the maximum load needed, the distance, and whether it is copper or aluminum. There are "voltage drop" calculators online that may help you. Conductor size may dictate later considerations such as conduit diameter, due to "fill" restrictions, or the means for overhead support.
How to add more circuits?
Rigid or flexible conduit methods allow for adding circuits at will without the labor or expense of excavating again. By installing pipe a size or two larger than required for the current project, or providing a 2nd pipe at the same time, there will be enough room to pull in additional conductors later. Speed future installations by always leaving an extra "pull wire" or string for use to connect either a rope or directly to a new cable when the time comes to expand the number of circuits. Multiple pipes must provided for other services - low voltage and signal services such as: communication (telephone or network), cable TV, satellite television, intercom, etc. services are not permitted in pipes that contain power. These cables must either be installed in a separate pipe or buried directly within a cable labeled as suitable for direct burial in earth. It should be obvious that there is a great deal of flexibility offered by the (multiple) pipe method.
How often should UF cable be supported?
UF cable must be supported every 30–36 inches (76.2–91.4 cm); just like NM cable. It does not need to be supported in the trench. This cable must be supported when run over concrete. This can be accomplished by securing wood (pressure treated if exposed to outdoors) to concrete and then securing the cable to the wood. If the cable may be subjected to physical damage, it should be "sleeved" in "Schedule 80" PVC pipe and terminated with proper pipe fittings (couplings, "LB" fittings, clips, expansion joints, etc.).
