Mounting Instructions

Mount the panel enclosure to a sturdy, flat wall surface before installing any electrical components.

Select Location: Choose a dry, accessible location per local code. Ensure adequate working clearance (typically 36" in front, 30" wide, 6.5' headroom).
Mark & Drill: Hold the empty enclosure against the wall. Level it and mark the mounting hole locations. Drill pilot holes.
Secure Enclosure: Using the provided screws, securely fasten the enclosure to wall studs or appropriate anchors.
Punch Knock-outs: Remove the appropriate knock-out plugs for your planned conduit or cable entry.

WARNING! Panel is heavy; use two people or proper support during mounting to avoid injury.

Electrical Wiring

With the panel securely mounted and power DISCONNECTED, proceed with wiring.

Feeders (Main Power):
- Route the incoming service feeder cables through conduit into the panel.
- Connect the two hot wires (typically black & red) to the main service lugs (L1 & L2).
- Connect the neutral wire (white) to the main neutral lug.
- Connect the equipment grounding conductor (bare or green) to the ground bar.
Branch Circuits:
- Route branch circuit cables through separate knock-outs.
- Connect the hot (black) wire from each circuit to the terminal on its corresponding circuit breaker.
- Connect the neutral (white) wire from each circuit to the neutral bar.
- Connect the ground (bare/green) wire from each circuit to the ground bar.

CAUTION! Torque all connections to manufacturer specifications. Do not double-tap lugs unless specifically rated for such use.

Circuit Breaker Installation

Install circuit breakers after all wiring is in place but before making final connections to the busbar.

Select Breakers: Use only breakers listed for use with this panel. Standard 1-inch wide, plug-on type.
Install: Hook the back clip of the breaker onto the busbar rail. Press the front of the breaker firmly onto the busbar until it snaps into place.
Arrange: Place higher-amperage or critical circuits near the main lugs if desired. Follow your planned circuit directory.
Connect Wires: Secure the circuit's hot wire under the breaker's terminal screw and torque to specification.

Final Assembly & Cover Installation

Inspect: Double-check all wire terminations for tightness and correct placement. Ensure no loose strands or debris are inside the panel.
Organize Wires: Neatly dress wires along the sides of the enclosure. Use wire ties if necessary, avoiding sharp bends.
Install Interior: If removed, carefully slide the interior assembly back into the enclosure and secure it.
Attach Cover: Place the hinged front cover onto the enclosure. Secure it with the provided screws.
Label: Complete the circuit directory label on the inside of the door, listing each breaker's number and the circuit it controls.

Testing & Commissioning

After installation is complete and before restoring power to connected loads:

Visual Final Check: Confirm cover is secure, no tools are left inside, and area is clear.
Breaker Positions: Ensure all installed circuit breakers are in the OFF position.
Restore Main Power: At the main service disconnect, carefully restore power.
Verify Voltage: Using a multimeter, verify correct voltage (approx. 120V L-N, 240V L-L) at the main lugs.
Energize Circuits: Turn on the main breaker (if applicable) and then individually turn on each branch circuit breaker, testing the connected outlet or fixture.

Tip: Have a helper test lights/outlets as you turn on each circuit.

Maintenance

Periodic inspection by a qualified electrician is recommended.

Annual Inspection: With power DISCONNECTED, check for signs of overheating (discoloration, melting), corrosion, or loose connections.
Cleaning: Use a dry, lint-free cloth to remove dust from the exterior and interior (power off). Do not use compressed air which can drive debris deeper.
Operational Test: Periodically test AFCI/GFCI breakers per manufacturer's instructions (usually a "TEST" button).

CAUTION! Never open the panel cover without first disconnecting power. Do not attempt to modify the panel interior.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power to any circuit	Main feeder not energized, main breaker tripped.	Verify upstream power is on. Reset main breaker (turn fully OFF then ON).
Single circuit dead	Circuit breaker tripped, loose wire connection, faulty load.	Reset the branch breaker. If it trips immediately, disconnect the load and inspect wiring for shorts/faults.
Breaker will not reset	Short circuit or ground fault present, faulty breaker.	Disconnect all loads on the circuit. Try resetting. If it holds, reconnect loads one by one to find the fault. If it still trips, replace the breaker.
Buzzing/humming from panel	Loose connection, faulty breaker, transformer hum (normal for some devices).	With power OFF, check torque on all connections, especially at the main lugs. If noise persists from a specific breaker, replace it.
Overheating at a connection	Loose terminal, over-torqued connection damaging wire, overload.	Disconnect power. Inspect connection for discoloration. Cut back damaged wire, re-strip, and reconnect to proper torque. Ensure load is within circuit rating.

Reset Procedure: For a tripped breaker, move handle fully to OFF position, then back to ON.

Service: For persistent issues, contact a qualified electrician or Volt Technical Support at 1-800-555-VOLT.
