Can I let my bank account go below 400k THB while holding a Non-B visa extension based on marriage to a Thai citizen?

The user is inquiring whether they can allow their bank account balance to dip below 400,000 THB for a short period while on a Non-B extension due to their marriage to a Thai national, provided that they restore the balance before their next visa application. Commenters clarify that the 400k must be maintained in a Thai bank account in the applicant's name for at least two months prior to application, although it can be zero for most of the year.
