Baseboard heater questions


I would like to wire 2 baseboard heaters in my basement. They are both 240v heaters. 1 is a 1500 watt and the other is a 500 watt. Each will have their own thermostat.

I currently have 100amp service to the house. There main panel is full.

A load center was added for a dishwasher.

My plan was to remove the current load center for the dishwasher and replace it with an 8 circuit, 4 place 125amp load center. I would then wire both heaters using 14-2 wire to the same 15amp double pole circuit breaker. I would move the current 20 amp circuit for the dishwasher to the new load center and there would then be 1 open spot in the new panel.

Does this sound ok? Are my wire sizes and breakers the right size? According to what I calculated I think it will work, but not sure when having different thermostats. Also what might happen if I were to add another 500 watt heater down the road?

Any help, confirmation, or guidance is highly appreciated.

I can take better pics if need be.

Can you post a picture inside the panel? What size wire and breaker is feeding the dishwasher panel now?

I can't tell what size wire it is by looking at it, sorry. There isn't any labeling on the part that I can see. The breaker for the dishwasher is a 20amp breaker. The wire size to the dishwasher is 12-2.

What breaker turns off the power to that panel?

That's not a 10 amp breaker.
The size of the breaker is on the handle, and will be 15 or 20.
The wire looks to be #6.
What size breaker feeds this small panel?

If the wire is stranded it's possibly 8 or 6. But I would read the jacket to be sure.

Who ever installed the subpanel installed it incorrectly/illegally. The grounds and neutrals have to be separated.

Sorry about that its a 20amp breaker not a 10.

From what I can see there is no breaker that feeds the small panel. The small panel is connected directly to the main power from the main panel.

The previous home owner I am assuming wired this himself. That is probably why it is incorrect/illegal. What should I do about that?

You can't use this panel it was installed incorrectly and should be removed by a qualified electrician.

They make Pushmatic tandem breakers. I don't know if your panel is rated for them and they are not cheap, but that is one suggestion.

The other is contact an electrical contractor for a quote on a new service.

It's possible that there are a lot of illegal gremlins inside that panel.

I would be really interested to see the inside of the main panel.

Many double taps in there. I would not use that panel the way it is. Looks like you could benefit from a panel upgrade so you have more room.
