Do you want to connect a washing machine and dryer to the same circuit? Fundamentally, NEN 1010 stipulates that large consumers should each have their own final circuit. However, there are situations where you can find a safe solution if only one conduit or circuit is available. Below, you can read what the standard says, where things can go wrong, and which options are safe. Also, read more about sockets and circuits in the washing machine cabinet. Do not confuse the electrical circuit with the drain; you can read about that in washing machine and dryer on the same drain.
What NEN 1010 briefly states
NEN 1010 is the installation standard for low-voltage installations. A practical rule of thumb from it: appliances with a power rating above 2000 watts should be on their own final circuit. A standard final circuit is 16A at 230V and can deliver approximately 3600 watts. Since washing machines and dryers often exceed 2000 watts, the basic principle is that they both need a separate circuit. This limits overload, voltage drop, and unwanted shutdowns.
Why putting them together on one circuit is usually not a good idea
A 16A circuit can handle approximately 3600 watts. A washing machine, depending on the program, often consumes 2000 to 2300 watts during heating. A dryer quickly ranges between 2000 and 3000 watts. When both appliances heat simultaneously, you exceed the circuit capacity, and the circuit breaker trips. Additionally, there are inrush current peaks that cause extra load. A double socket does not help - it remains the same circuit. Read how to safely install a socket in the washing machine cabinet. Apart from comfort and malfunctions, you also run a risk in case of damage if it turns out that the installation was not carried out in accordance with the standard.
Safe options when you are limited in circuits
Installing two separate final circuits
This is the best and most future-proof solution. Your washing machine and dryer each get their own 16A final circuit with earthing, according to NEN 1010. This allows you to use both appliances simultaneously without problems, without unnecessary shutdowns or overloads. During renovation, this is the moment to plan extra conduits and circuits for large consumers. If necessary, use this checklist for the installation of a washing machine cabinet.
Combiner switch or power distributor on one circuit
If you only have one circuit available, an approved combiner switch can offer a solution. Such a switch monitors the power and prevents the washing machine and dryer from simultaneously demanding their peak power. One appliance gets priority, the other waits or pauses automatically. It is important that the solution is certified and professionally installed. Realize that your appliances cannot run at full power simultaneously - that is precisely the safety function. Additionally, check whether water and electricity meet the requirements for a washing machine cabinet.
Cooker circuit as an alternative in specific cases
A cooker circuit consists of two mechanically coupled 16A circuit breakers. In some situations, installers choose such a coupled double final circuit to power two heavy consumers separately. This can be a safe route provided it is designed and installed fully in accordance with NEN 1010, including correct wiring, wall sockets, and protective devices. Always have this assessed and carried out by a recognized electrician - it is custom work and not applicable in every home.
Are you placing the appliances in one cabinet? Then pay attention to ventilation, vibration, weight, and the divisible power on the circuit(s). For practical steps, see Connecting a washing machine in a cabinet. Do you prefer to place them separately, but compactly? Then view the points of attention for washing machine and dryer next to each other in a cabinet.
Frequently asked questions
Can a washing machine and dryer be on one circuit?
In principle, not desirable, because both are large consumers. According to NEN 1010, each appliance should be on its own final circuit. Only with a certified combiner switch that prevents simultaneous peak consumption can you safely use them on one circuit.
Can I connect a washing machine and dryer to the same socket?
A double socket remains one circuit. It seems practical, but with simultaneous consumption, you quickly exceed the approximately 3600 watts of a 16A circuit. Opt for two final circuits or an approved combiner switch as a temporary solution.
Which appliances need to be on a separate circuit?
Rule of thumb: everything above 2000 watts. Think of washing machine, dryer, dishwasher, oven, Quooker, and electric hob. This limits overload and ensures your installation complies with the standard.
Why are washer-dryer combos not popular?
They save space but often have longer program durations, lower drying capacity, and more wear and tear due to combined use. Separate appliances usually perform better and offer more flexibility in energy use and planning.
