Let's break down the factors involved in whether two electricians could realistically get this done in one 8-hour day

Factors Favoring a One-Day Installation:
Simplicity of the Installation

The panel looks relatively straightforward, meaning it is a simple swap out.

Factors Against a One-Day Installation



Delivery and Unpacking

Moving a large and heavy panel safely from the delivery point to its installation location can be time-consuming, especially if there are stairs, tight corners, or other obstacles.

Complexity of the Existing Wiring

The biggest unknown is the state of the existing wiring. If the wiring is old, brittle, improperly sized, or poorly labeled, it will significantly slow down the process.

Permitting and Inspections

Depending on local regulations, you might need a permit for this type of work. While you may not need a day of downtime for this, it is good to consider.

Troubleshooting

Unexpected problems always arise. There could be issues with the main feed, existing circuits, or discovering hidden code violations that need immediate correction.

Breaker Configuration

The new panel might have different breaker slots or configurations compared to the old one. This could require re-arranging circuits.

Travel time

Consider how far you are traveling and if you are required to travel from a company or other location.

Realistic Scenario



If everything goes smoothly, two experienced electricians with a good understanding of the existing system and good tools can likely get the panel installed and wired up in a single 8-hour day. However, this assumes: The delivery is straightforward. The existing wiring is in good condition and well-labeled. There are no unexpected problems. There are no major code violations that need immediate correction. There is minimal travel time They have all necessary materials on hand.

Important Considerations



Safety First

Working with electrical panels is dangerous. Safety should always be the top priority.

Communication

Clear communication between the electricians is crucial for efficient work.

In conclusion, while it's possible for two electricians to install the panel in one day, it's not a guarantee. It heavily depends on the factors mentioned above. It's always better to overestimate the time required and avoid rushing the job, as that can lead to mistakes and safety issues. Flag for review
