Timemore Sculptor 078 power doubt

#1: Post by **Raglo** » March 21st, 2023, 1:38 am

When I connect both the Stagg EKG and Sculptor to a 230V 15A power socket I can hear the motor struggle to reach full rpm. Is this because both appliances combined require more than 15A of power? I also feel like the grounds produced are sub optimal when I grind coffee while the Stagg is is on. Grinding while off produces much better coffee. Has anyone else had this issue and is the only solution to put them on separate sockets?

UPDATE: I've done more testing and it turns out that my Stagg EKG seems to be the culprit here. The sculptor doesn't flinch even with an 1800W kettle but the moment the EKG goes over 90°C this happens. I made a video which I've linked to below. If you turn the sound on then you'll be able to hear what I'm talking about. Any idea what could be going on here?

That sounds odd the EKG kettle only require about 5amp the grinder only about 2amp. Meaning even a 10amp should handle it without any issues.

I run mine on a 10amp with my grinder, I even ran it with a grinder as well as a flair58 no issues on 10amp.

It most likely sounds like there is a problem in your electrical installation, try moving it to another group and see if the issue stand.

Perhaps you have more outlets tied to that 15A circuit than you think?

That doesnt sound right. I am using my 078 since november plugged together with my timemore kettle 600ml - 1000W.

Together they can draw max 1.4 kw that is nothing.

Try them in a different plug, not in the same place but in another room.

UK, ring wiring by any chance?

IDK if the wiring in the UK is different but usually overdrawing a circuit should just cause the breaker to trip (or a fire in your walls in the worst case)

Easy to confirm. What's the voltage read on this circuit in the various scenarios?

Well that or he uses old fabric insulated brittle copper wires, I lived in flats with that and had loads of issues and an old fuses breaker.

Needles to say it was also dangerous

I've added this info to the opening post too just to make things easier.

Well you kettle is defective, and your circuit breaker should have been kicking in, there might be issues in its wiring or other parts. Either way stop using it and put it in for repairs.
