does the same 6% contribution limit apply to the sep contributions that apply to p/s contributions if the employer is contributing more than 25% ofpay to a DB plan and the plan is not pbgc covered?
I only can find mentions of DC issues when i see combo plans on irs.gov or any other site.

thanks

Yes. IRC 404(h)(3).

If a 5305 model SEP, then you can't contribute to it while participants are accruing a benefit under another plan anyway.

ok, thanks
