When a bill of exchange is protested for nonacceptance, the same rate of damages is allowed as in the case of a protest for nonpayment; and such damages are in the place of all charges, except costs of protest, incurred previous to and at the time of giving notice of nonacceptance; but the holder is entitled to recover legal interest, exclusive of the damages, upon the amount of the principal sum from the time when the same would have become payable, if accepted, interest on the damages from the demand of acceptance and the costs of protest.
