Apartment Electrical Plan Before Renovation

Apartment electrical work must be planned before chasing and finish work: separate lines for kitchen, bathroom, and heavy appliances; a panel with RCDs and differential breakers; outlets based on how you actually live — not “one per room.” Rework after walls close costs multiples more than a proper scheme at renovation start.

Profmaster has delivered turnkey apartment renovation in Moscow and the region since 2006. Below is how to split electrical work by zone, what to put in the estimate, and what to capture on camera before walls close. This is practical guidance — it does not replace a licensed design, but it helps avoid typical budget leaks.

If layout changes in parallel, align electrical work with layout approval and wet-area rules.

Why electrical work cannot be “added later”

In short: wiring lives inside walls, floors, and ceilings. Mistakes show up after paint, when change is painful.

Typical consequences of late planning:

• not enough outlets behind kitchen backsplash;
• no line for AC or lit curtain cornice;
• breaker trips when oven and kettle run together;
• finished bathroom tile must be opened;
• grounding missing where needed;
• unknown cable location when drilling.

If you simplify: electrical work is an apartment map. Without the map, every drill risks hitting a cable.

Main risk: planning outlets on empty walls without furniture and kitchen layout.

Outlets and lines by zone

In short: each zone has its own load and moisture profile. Putting “everything on one breaker” is a bad idea.

Zone	Outlets and feeds	Circuits and protection	Comment
Kitchen	Hob, oven, fridge, dishwasher, microwave, small appliances, hood	Separate lines for heavy appliances; RCD/differential on groups	High load, moisture, grease
Bathroom	Washer, towel warmer, shaver zone, smart toilet	RCD required; IP-rated outlets by moisture zone	Moisture protection and service access
Hallway	Vacuum, chargers, router/intercom, sometimes panel	Separate lighting and outlet group	Daily convenience
Living room	TV, media, chargers, floor lamps, sometimes AC	Lines for appliances and low voltage	Plan spare capacity behind furniture
Bedroom	Bedside, chargers, sconces, motorized curtains	Lighting separate from outlets	Do not depend on one switch
Balcony / loggia	Heat, light, sometimes outlet	Moisture protection where needed	Check glazing constraints

Merging kitchen and living room adds longer routes, islands, and more circuit groups.

Panel, circuits, and protection

In short: a modern panel is not “a box of breakers” — it protects people and equipment.

Typical capital-renovation package:

• main breaker and meter per utility rules;
• differential protection (RCD/differential breakers);
• separate breakers for lighting and outlets;
• lines for heavy consumers;
• 20–30% spare space in panel for future needs;
• labeling on every circuit;
• schematic in panel and copy for owner.

Circuit	Typical consumers
Apartment lighting	Fixtures, pendants, LED strips
Living room outlets	TV, chargers, small appliances
Kitchen — heavy appliances	Hob, oven
Kitchen — outlet group	Small appliances, backsplash
Bathroom	Washer, towel warmer, zoned outlets
Air conditioning	Separate line per indoor unit
Low voltage	Internet, cameras, intercom — separate from power

In resale apartments, old panels with aluminum wire and junction twists are a reason to plan full replacement, not “add a few outlets.”

Common mistakes: why it gets expensive and what to do instead

Mistake	Why it costs later	Correct approach
One line for whole kitchen	Overheating, tripped breakers, backsplash rework	Separate lines for heavy appliances
Outlets without furniture plan	Extension cords, opening finished walls	Kitchen and furniture plan before chasing
No RCD in bathroom	Shock risk, panel rework	RCD/differential and IP outlets by zone
Chasing load-bearing without project	Approval rejection, structural risk	Routes through partitions/floor per project
Undersized cable	Losses, heating, fire risk	Sizing by load and line length
No separate low-voltage routing	Interference, equipment failure	Separate cable routes
No photos or schematic	Drill into cable, disputes	Photos, plan, labels before closing
“Electrician will figure it out”	Chaotic routes, no warranty	Approved scheme in estimate and contract

Main risk: saving on panel and circuit count. The estimate difference upfront is smaller than opening finish work a year later.

What belongs in the electrical estimate

In short: the estimate should not have one line “electrical 150,000 RUB” with no breakdown.

Minimum line items:

1. Project or schematic — outlet, switch, circuit, and panel plan.
2. Panel and protection — enclosure, breakers, RCD/differential, busbar, labels.
3. Cable — type, cross-section, length by group.
4. Conduit, trays, fixings — protection and fire requirements.
5. Outlets, switches, frames — quantity and class.
6. Chasing and drilling — meters and wall material.
7. Assembly and install — termination, grounding.
8. Testing — line checks, phasing, acts if required.
9. Low voltage — if in scope: internet, TV, sensors.
10. Contingency — for nodes found after opening walls.

How to read that inside full renovation: how to read a renovation estimate. Overall budget guide: capital renovation calculator — final amount after site visit.

If you simplify: a good electrical estimate answers “how many lines, what cross-section, and where they go.”

Lighting and switches: scenarios, not one chandelier

In short: lighting shapes how space feels; plan it with electrical work, not after paint.

Useful scenarios:

• several living room modes: general, accent, evening;
• separate line for kitchen backsplash lighting;
• bedside sconces with switches at door and headboard;
• prep for motorized curtains;
• motion sensors in hallway;
• heated floor with separate thermostat and sensor.

On designer renovations, lighting scenarios often sit in the design project — but execution must still be in the electrical scheme before chasing.

Photo checklist before walls close

Save to cloud before plaster, drywall, and tile:

• General view of each room with wires and conduit.
• Panel: each circuit labeled as agreed.
• Kitchen: backsplash outlet heights from floor and countertop.
• Bathroom: outlets, towel warmer, washer feeds.
• Hallway: low-voltage panels, router, intercom.
• AC routes to outdoor unit locations.
• Crossings with plumbing — to avoid drilling later.
• Feeds for fixtures, pendants, LED strips.
• Slab and load-bearing penetrations if any.
• Paper/PDF plan tied to walls.
• Hidden-work acceptance with contractor.

Main risk: “the scheme is in the electrician's head.” In three years, even they will not have it.

Link to layout changes and noisy work

Moving kitchen, bathroom, or removing walls changes routes and line length. That affects:

• cable cross-section;
• panel location;
• chasing feasibility;
• noisy work schedule;
• approval requirements.

Design electrical and layout as one package, not two disconnected stages.

Customer checklist

• Furniture and kitchen layout plan exists.
• Full appliance list with power draw prepared.
• Panel location and expansion reserve defined.
• Outlets and lighting agreed by zone.
• Estimate breaks down lines, cable, panel, outlets.
• Bathroom includes RCD and moisture-rated points.
• Low voltage separated from power routes.
• Chasing aligned with layout approval.
• Hidden-work acceptance scheduled.
• Photo archive prepared before walls close.

When to contact Profmaster

Contact Profmaster if you are doing capital renovation with full electrical replacement and want the scheme to match layout, kitchen, and bathroom — without rework after finish work.

We are a fit when:

• turnkey renovation with MEP, rough, and finish work is needed;
• electrical scheme must be fixed before walls close;
• complex kitchen, multiple AC units, or scenario lighting is planned;
• renovation runs in resale stock with old wiring;
• you want one team, not an electrician disconnected from finishing.

The company has worked since 2006. We fix MEP scope in estimate and contract, not “on site as it goes.”

Request via services or contacts.

Summary

Apartment electrical work is the foundation of comfort and safety: outlets, panel, and circuits belong in the plan before renovation, by zone and real appliances, with RCD protection and a clear schematic. Photos and labels before walls close save money on every future drill.

In short: furniture and load plan first, then schematic and estimate, then chasing. That way electrical work serves you — not extension cords and rework.
