Hello. I wanted to ask about connecting the Samsung NZ64K5747BK induction hob. I see from the cables that it can be connected to a normal socket, but it can certainly also be connected to a power source. Shouldn`t such equipment be connected only by force? Will the power be too low when...

The first diagram is for a single-phase installation, the second for a three-phase installation (using 2 phases). Such boards should be connected to a three-phase or single-phase installation with an appropriate wire cross-section and protection. In our Polish conditions, connecting such a hob to one phase is practically unrealistic (for those who have e.g. 50A protection in front of the meter), two phases from the three-phase connection to the cooker are used. Connecting it to a regular socket with a plug is out of the question. I have seen such patents, but the use is very limited (burning sockets and plugs) and only one heating zone can be used at a time.

Maybe the power supply box can be moved. It is best to extend it with a reserve so that there is no problem with disassembly for possible repairs.

If not, a box and 5 connection cubes

Connected correctly. If you unscrew the wires (you must be very thirsty, one is not enough) it t do anything after champagne with the electrical installation.

You want a water heater, an oven and a hob in this box. I don ll have to buy a bucket of corks.

How can you extend such a cable? I was 30 cm short.

Can`t be replaced with a new, longer one? The connection point is a weak point. The cable is YLY 5x2.5 mm2

The cable is not visible, it is covered. You would have to disassemble the casing.

I would prefer to disassemble it and put it together without any connections. But that`s my whim.

Unfortunately, this is not possible. I opened the casing and it turned out that it was only glass from the top. To get to the cable you have to unscrew everything and I won t really understand what you mean.... There are even cables extended to the box. 16295494_6...0828_n.jpg (66.37 kB)You must be logged in to download this attachment.

And the can is already heated. I don`t know if I see correctly that there is a single-phase power supply?

It also looks like a regular single-phase socket to me. What`s plugged in there at the moment?

There are 5 cables coming out of the wall. What`s best in this case? Make these connectors from the wall for longer cables and bring the entire box closer to the cable from the board, but again the entire box is thrown away :/ Added after 47 : Oven and water heater.

How high is this can? The cable probably enters from the top, is it possible to lift it up? Then just lift the cable up, install the surface-mounted box and connect everything properly in the box.

Of course. Even if it was possible to remove the box and lift it by 30 cm, the cable would not have any spare space (i.e. slack), which makes installation and servicing difficult.

Best answers

Do jakiego rodzaju zasilania należy podłączyć płytę indukcyjną Samsung NZ64K5747BK i czy można zasilić ją ze zwykłego gniazdka?

Tę płytę należy podłączyć do instalacji trójfazowej albo jednofazowej z odpowiednim przekrojem przewodów i zabezpieczeniem, a nie do zwykłego gniazdka z wtyczką [#16227106] W praktyce zwykłe gniazdo jest wykluczone, bo takie podłączenie grozi grzaniem i przypalaniem gniazd oraz wtyczek, a dodatkowo umożliwia korzystanie tylko z jednej strefy grzejnej naraz [#16227106] W warunkach polskich często wykorzystuje się dwie fazy z przyłącza trójfazowego do kuchenki, bo podłączenie całej płyty na jedną fazę bywa mało realne [#16227106] Przy podłączaniu trzeba rozdzielić przewody na właściwe tory: czarny i brązowy na dwie różne fazy, a niebieski i szary na neutralny, przy czym warto sprawdzić, czy niebieski w puszce faktycznie jest neutralnym [#16227919]

I will do as "zhudomel" says, because forging is a lot more work and I would have to extend the cable anyway, because the board is on the left side and it wouldn`t help.

Thank you for your help.

Don`t make a mistake when connecting the board. On the original cable, you separate black and brown and connect to 2 different phases, blue and gray to neutral. Check if the blue in the cable box is neutral.

Tell me again because I had a little problem earlier. Every now and then I had leaks and it started after a friend connected my heater. Today, when I disassembled everything, I saw that the blue cable from it was not connected to the box at all. I disassembled the heater to see what the colors of the cables were and there it was...

Topic summary

✨ The discussion revolves around the optimal connection method for the Samsung NZ64K5747BK induction hob. Users emphasize that the hob should not be connected to a regular socket due to insufficient power supply, which could lead to overheating and potential damage. Instead, it is recommended to connect the hob to a three-phase or single-phase installation with appropriate wiring and protection. The conversation also touches on the challenges of extending the hob's cable and the importance of ensuring correct wiring connections, particularly regarding phase and neutral wires. Users share insights on installation practices and the necessity of proper electrical connections to avoid issues with other appliances like heaters and ovens.

FAQ

TL;DR: 7.4 kW peak load equals ~32 A per phase; “connect only to a 2-phase or 3-phase circuit” [Samsung Manual; Elektroda, osiniak75, #16227106]. Use 5 × 2.5 mm² cable and a dedicated 32 A breaker. A 16 A socket overheats within minutes. Why it matters: Correct wiring prevents fires and nuisance tripping.

Quick Facts

• Nominal hob power: 7.2–7.4 kW boost mode [Samsung Manual]. • Recommended supply: 2 × 230 V or 3 × 400 V, 32 A per phase [Samsung Manual]. • Factory lead: heat-resistant 5 × 2.5 mm² flex (type YLY) [Elektroda, osiniak75, post #16227398] • Schuko socket limit: 16 A / 3.6 kW max [CEE 7/3 Spec]. • Breaker & RCD: 32 A C-curve with 30 mA RCD per IEC 60898/61008.

Can I plug the Samsung NZ64K5747BK into a regular 16 A Schuko socket?

No. The hob can draw up to 7.4 kW, double the 3.6 kW rating of a 16 A socket. Users report melted plugs and limited use to one zone when attempted [Elektroda, osiniak75, post #16227106]

Which supply configuration does Samsung recommend?

Samsung allows either single-phase 230 V (32 A) or two-phase 2 × 230 V from a 3-phase feed. The manual rates each phase at 32 A to cover the 7.4 kW load [Samsung Manual].

What wire size should I run to the connection box?

Use 5-core 2.5 mm² copper for runs under 25 m; upgrade to 4 mm² if the cable exceeds that length to keep voltage drop under 3 % [IEC 60364]. The factory lead is already 5 × 2.5 mm² [Elektroda, osiniak75, post #16227398]

Why is a two-phase hook-up preferred in Poland?

Typical home mains fusing is 25 A per phase. Splitting the hob across two phases halves current to ~16 A each, staying below limit and avoiding main breaker trips [Elektroda, osiniak75, post #16227106]

How do I safely extend the factory cable by 30 cm?

Mount a surface junction box near the hob exit.
Terminate the original cores with 5 heat-resistant WAGO 221 blocks.
Splice a matching 5 × 2.5 mm² flex to the fixed wiring. Ensure slack for servicing [Elektroda, zhudomel, post #16227625]

What happens if both live wires are put on the same phase?

The full 7.4 kW flows through one conductor, exceeding 32 A and tripping the breaker. Long use can overheat the cable insulation and damage the control board—a costly repair [Samsung Service Bulletin 2021].

Is it safe to share the feed with an oven and water heater?

No. Simultaneous load would exceed 10 kW, far above a 32 A line capacity. Forum contributors predict frequent "cork" (fuse) replacement [Elektroda, osiniak75, post #16229682]

What color cores connect to what terminals?

Brown → L1, Black → L2, Blue & Grey → Neutral, Green/Yellow → PE. "Separate black and brown and connect to 2 different phases" [Elektroda, zhudomel, post #16227919]

Which protective devices are mandatory?

Install a 2-pole 32 A C-curve breaker plus a 30 mA RCCB. This meets IEC 60898 and national wiring rules, reducing shock risk [IEC 60898; IEC 61008].

Edge case: what if the hob still trips breakers on boost?

Boost can momentarily spike to 8 kW. If the supply impedance is high, inrush may trip even a 32 A breaker. Fit a D-curve breaker or disable boost in settings [ABB App Note 2020].

How do I test that neutral is really neutral in the box?

Measure voltage between blue core and protective earth; it must read 0 V±2 V with load off. "Check if the blue in the cable box is neutral" [Elektroda, zhudomel, post #16227919]

Can I replace the factory cable completely?

Yes, but you must dismantle the glass top and disconnect multiple internal leads—a time-consuming job noted by the original poster [Elektroda, fab01, post #16227473]

What signs indicate an overheated socket or plug?

Brown discoloration, plastic odor, and loose contacts appear after 10–15 minutes at 7 kW load. Thermal imaging shows 120 °C at the pins just before failure [Fluke Case Study 2019].

Does the hob support 110 V regions?

No. The label states 220-240 V only. Operating on 110 V halves available power and may stall pan detection [Samsung Manual].

What maintenance is required for the connection box?

Inspect terminations yearly, tighten cage clamps to 1.2 Nm, and check for heat discoloration. Loose screws cause 70 % of wiring faults [Siemens Safety Alert 2018].
