Calculators
Cable cross-section
by power and length: allowable current (PUE) + voltage drop + breaker rating
Panel configurator
Allocated power → main breaker, modules, RCDs
Breaker selection
Load + cable → breaker rating
Appliance consumption
kWh/month and cost per appliance — find the hungriest
Grounding loop
Soil type → electrodes for target resistance
Lighting
lux norms by room type → luminous flux and fixture count
Outlet planning
Room + area → outlets and code heights
Kitchen wiring
Dedicated lines for heavy appliances, cable sizing, RCD and outlet plan for the kitchen.
UPS sizing
Load + runtime → UPS VA and battery Ah
Home generator
sizing with starting currents, fuel use, cost per day
Solar station
sizing by consumption, regional yield, payback
Electric vs gas heating
kW by heat loss, seasonal bill, gas comparison
Floor heating
Area + mode → watts, current, circuit
Smart home wiring
Neutral in switch boxes, Zigbee/Wi-Fi/KNX protocols, low-voltage and backup power.
Electrical safety
Bathroom zones, RCD vs breaker, child safety and signs of bad wiring.
Electricity
Appliance energy usage calculator
Day/night meter
does a two-zone meter pay off for your consumption profile
Low-voltage plan
Rooms/TV/cameras → cable and switching
Workshop wiring
Three-phase for machinery, moisture & dust protection, lighting and inrush currents.
Electrical documents
Wiring diagram, acceptance act, measurement protocols and electrician contract.
