Here are some conduit types you can use outside:

• Intermediate Metal Conduit (IMC): Strong and does not rust.
• PVC Conduit: Light, does not carry electricity, good for wet places.
• Electrical Metallic Tubing (EMT): Thin, needs watertight fittings.
• Rigid Nonmetallic Conduit (RNC): Smooth and bends for underground.
• Liquid-Tight Flexible Metal Conduit (LFMC): Bends and keeps water out.

Tip: Always use cables made for outside, like UF cable for burying, and dig to the right depth.

Main Power Connection

Connecting the main power is a very important step. You must be careful to avoid mistakes and danger.

1. Turn off all power by flipping the main breaker.
2. Take off the panel cover slowly so you do not break anything.
3. Use a voltage tester on each breaker to make sure power is off.
4. Knock out a hole in the panel for the new wire.
5. Put in a plastic clamp and push the wire through it.
6. Strip the wire jacket and cover the ends with tape.
7. Push the wire into the clamp, leaving at least 1/4-inch of jacket inside.
8. Hold the wire outside with an insulated staple.

Grounding and Bonding

Good grounding and bonding keep you safe from shocks. The National Electrical Code tells you how to do this step.

• Use rods, pipes, or plates for grounding. Take off any paint or coating first.
• Put rods or pipes at least 2.44 meters deep. If you hit rock, put them at an angle or lay them flat at least 0.75 meters deep.
• Keep extra rods at least 1.8 meters apart.
• Use ground rod clamps that are made for being buried.
• Every building with its own panel needs a grounding system connected to the equipment grounding wire.
• Do not connect the grounded wire to the ground rod at the building.
• Pick the grounding wire size based on the biggest wire you use.
• Use copper, aluminum, or copper-clad aluminum for grounding wires.
• Test the ground after you finish. Try for less than 25 ohms, but lower is better for big jobs.

Tip: Use ground rings and special welds for extra safety in big or important jobs.

Breaker and Circuit Setup

Setting up breakers and circuits takes planning. You must match the panel and breaker, figure out the load, and follow the rules.

1. Use a NEMA 3R panel for outside.
2. Run wires in conduit from the top of the panel to a box, then use THHN wire to the breakers.
3. Hold all wires with plastic clamps.
4. Do not touch live bus bars or lugs.
5. Use the right tools, like wire strippers and testers.
6. Find out who made your panel and what model it is. Only use breakers that fit.
7. Turn off all power before you work inside the panel.
8. Plan for lights, outlets, and big appliances. Do not use more than 80% of the panel’s power.
9. Add up your total load. For example, a 10,800 VA load on a 240 V panel is 45 amps.
10. Count all circuits, including lights, outlets, and special equipment.

Here is a sample load calculation table:

Load Component	Calculation Basis	Approximate Load (VA)
General lighting and receptacles	Square footage x 3 VA/sq ft	4,500
Small appliance circuits	2 x 1,500 VA	3,000
Laundry circuit	1 x 1,500 VA	1,500
Gas furnace	1 x 1,500 VA	1,500
Microwave oven	1 x 1,500 VA	1,500
Electric water heater	1 x 3,000 VA	3,000
Total existing load		10,800
Convert to amperes	10,800 VA / 240 V	45 Amps

Note: If you are not sure about any part, ask your city or a licensed electrician.
