Quick Guide
  • The Sinking City 2 fuse box is beside the inactive floodgate switch near the bridge.
  • Electrical Fuses are inside the locked Radio Store and require an alternate route through Apartments 5 and 6.
  • Investigation Space connects two notes and awards a Talent Point before the final repair.
  • Fuse puzzle requires placing three Electrical Fuses in the correct panel positions.
  • Next objective is to pull the floodgate lever and return to the boat.

The Sinking City 2 fuse box location

The The Sinking City 2 fuse box appears during the Opening the Floodgate objective. After reaching the district by boat, dock near the gate and enter the building through the window. Cross the bridge and continue until you find Harry on the ground beside the floodgate controls.

Try the switch first. It will not operate because the mechanism has no usable Electrical Fuses. The Fuse Box is mounted beside this switch, but repairing it immediately is not possible. You must first enter the nearby buildings, locate the fuse supply, and complete the investigation clues connected to the gate.

The most important landmarks are the bar, the apartment building, and the Radio Store. The bar is useful as a navigation anchor, while the apartment building provides the route into the locked store.

Navigation Tip

Use the bar and the floodgate bridge as fixed landmarks. If you become turned around, return to the road near the bar before checking the apartment route.

How to get the Electrical Fuses

The Electrical Fuses are inside the Radio Store, but the front door is locked. Do not spend time searching for a key at the entrance. The intended route passes through the apartment building beside the bar and uses a hole in the floor to reach the store from inside.

Begin by entering the half-open apartment entrance next to the bar. Search the small room on the right for handgun ammunition and the building map. Then follow the hallway upstairs, where Apartments 5 and 6 are located.

Apartment 6 contains a locked kitchen safe and the To Martin note. The safe is not required for the Fuse Box repair, so leave it for later unless you want to complete the nearby clue chain first. Enter Apartment 5, break the barrels near the floor opening, and drop into the lower area.

Continue through the lower passage and crawl through the opening. Before leaving the route, collect the Gate Fuses and Wires note from the table. This note is important because it works with the earlier Gate Switchboard note in Investigation Space.

After entering the Radio Store, collect the Electrical Fuses from the shelf. A cutscene follows, and the first combat encounter begins. Defeat the creature, then move the obstruction near the exit so you can return to the main road.

1

Enter the apartment building

Leave the floodgate area and follow the road back toward the bar. Enter the half-open apartment building beside it, then collect the map in the small room on the right.

2

Reach Apartment 5

Go upstairs past Apartments 6 and 5. Inspect Apartment 6 if desired, then enter Apartment 5 and kick the barrels beside the hole in the floor.

3

Follow the lower passage

Drop through the hole, collect the Chemicals, crawl through the opening, and pick up the Gate Fuses and Wires note from the table.

4

Enter the Radio Store

Continue through the opening into the store. Loot the handgun ammunition, inspect the nearby note, and collect the Electrical Fuses from the shelf.

5

Survive the encounter

Fight the creature after the cutscene, then clear the exit obstruction and return to the road leading toward the bar and floodgate.

Resource Warning

The Radio Store pickup starts the first combat encounter. Keep some handgun ammunition available, but prioritize weak points and finish stunned enemies with melee attacks when safe.

Connect the gate clues before repairing the panel

Before returning to the floodgate, use Investigation Space to connect the two gate-related documents. The first document is the Gate Switchboard note, found on the bar counter. The second is the Gate Fuses and Wires note, found in the lower passage reached through Apartment 5.

Opening Investigation Space and linking these documents produces a Talent Point. This deduction is separate from the physical Fuse Box repair, so it is worth completing before you pull the gate lever.

The clue connection also provides useful context for the repair. It confirms that the floodgate mechanism depends on three Electrical Fuses and that the panel must be restored before the switch can function.

From A SisterNear the Radio Store cash counterReveals the Apartment 6 safe code

The Radio Store also contains the From A Sister note. Connecting it with To Martin reveals that the Apartment 6 safe uses 1908, the opening year of the Radio Store. This safe is optional for the floodgate objective, but it provides Dolorocide Pills and handgun ammunition.

The safe can also trigger additional monsters after opening. If your immediate goal is the floodgate, collect the fuses first and return to the safe only when you are prepared for another encounter.

Best Order

Collect both gate notes, connect them for the Talent Point, take the Electrical Fuses, then decide whether to open Apartment 6 before returning to the floodgate.

Solve the Fuse Box puzzle

Return to the floodgate bridge after leaving the Radio Store. The route through the bar and main road is usually quiet, although enemies can appear around the store and on the approach to the bridge.

Interact with the Fuse Box beside the floodgate switch and use the three Electrical Fuses. The panel then changes into a placement puzzle. Your objective is to install all three fuses in their correct positions so the gate mechanism receives power.

The repair uses three Electrical Fuses rather than a single replacement part. Check the panel carefully and compare the visible connection layout before confirming each placement. The correct arrangement is shown in the demo walkthrough’s puzzle reference image; use the panel’s wiring pattern and the matching visual layout rather than guessing randomly.

Supply the partsUse the three Electrical FusesAll repair pieces become available
Match the layoutPlace each fuse in the correct positionCircuit arrangement is accepted
Restore controlLeave the panel after the puzzle resolvesFloodgate switch becomes usable

If the placement does not register, remove the fuse and inspect the socket orientation again. Confirm that every slot is filled and that the visible wiring matches the required configuration. The puzzle is not solved by merely inserting the correct number of parts; their positions matter.

Once the mechanism is repaired, interact with the lever beside the panel. The floodgate opens, allowing you to return to the boat and continue toward the Library Annex.

Puzzle Reminder

The three Electrical Fuses are collected together in the Radio Store. The challenge at the floodgate is their placement, not finding additional replacement parts.

After the floodgate opens

Pulling the lever completes the Fuse Box objective, but the route back to the boat is not entirely safe. As you leave the bridge, another monster can ambush Calvin Rafferty. Keep moving through the opened route, create space when necessary, and avoid spending ammunition on enemies that can be bypassed.

Return to the boat and sail through the newly opened gate. Continue across the flooded district until you reach another floodgate near the Library Annex. Dock at the nearby pier, climb the wooden stairs, and enter the building through the opening.

The next area introduces more exploration, combat, and investigation objectives. The Library Annex route eventually leads into the main library, where you can find maps, Codex Entries, supplies, and the path toward the Restricted Section.

Fuse Box Objective Checklist:

  • Reach the inactive floodgate switch near the bridge
  • Enter the apartment building beside the bar
  • Collect the Gate Fuses and Wires note
  • Take the Electrical Fuses from the Radio Store
  • Connect the two gate notes in Investigation Space
  • Place all three fuses and pull the floodgate lever
Post-repair objectiveRoute detailPreparation
Leave the bridgeFollow the route back toward the boatWatch for the ambush
Reach the boatContinue through the opened gate areaKeep healing items ready
Sail onwardFollow the flooded districtWatch for the next floodgate
Enter Library AnnexDock at the pier left of the gateSearch nearby rooms for supplies

For a visual route reference covering the demo’s floodgate and Library Annex progression, see the The Sinking City 2 Walkthrough – Demo. The guide also covers the connected apartment route, Radio Store encounter, and transition toward the library.

Route Efficiency

The safest progression is to finish the gate deduction before the final repair, then return directly to the boat after opening the floodgate unless you are completing optional apartment content.

The Sinking City 2 fuse box FAQ

Q: Where is the The Sinking City 2 fuse box?

It is beside the inactive floodgate switch on the bridge near the opening district. You reach it after returning from the Radio Store with the Electrical Fuses.

Q: Where do I find the Electrical Fuses?

The Electrical Fuses are inside the Radio Store on a shelf. Because the front door is locked, enter the nearby apartment building, pass through Apartment 5, and use the lower passage to reach the store.

Q: Do I need to open the Apartment 6 safe to repair the Fuse Box?

No. The Apartment 6 safe is optional. Its code is 1908, revealed by connecting the To Martin and From A Sister notes, and it contains Dolorocide Pills and handgun ammunition.

Q: What should I do after solving the Fuse Box puzzle?

Pull the floodgate lever, return to the boat, and sail through the opened route toward the Library Annex. Be ready for an ambush on the way back.

Missed Item Check

If the Fuse Box will not accept a repair, verify that you collected the Electrical Fuses from the Radio Store and did not leave the Gate Fuses and Wires note behind.
