Conn. Gen. Stat. § 9-258

(b) For municipalities with one voting district, the election officials of such polling place shall be electors of the state and shall consist of (1) one moderator, (2) at least one but not more than two official checkers, (3) at least one but not more than two voting tabulator tenders for each voting tabulator in use at the polling place, and (4) at least one but not more than two ballot clerks. Additionally, such election officials may consist of two registrars of voters of opposite political parties, or two assistant registrars of voters of opposite political parties, as the case may be, subject to the requirements of sections 9-259 and 9-439 , provided if the registrars of voters are present in the polling place, they shall appoint at least one designee to be present in their office. A known candidate for any office shall not serve as an election official on election day or serve at the polls in any capacity, except that (A) a municipal clerk or a registrar of voters, who is a candidate for the same office, may perform his or her official duties, and (B) a deputy registrar of voters, who is a candidate for the office of registrar of voters, may perform his or her official duties. If, in the opinion of the registrar of voters, the public convenience of the electors in any voting district so requires, provision shall be made for an additional line or lines of electors at the polling place and, if more than one line of electors is established, at least one but not more than two additional official checkers for each line of electors shall be appointed and, if more than one tabulator is used in a polling place, at least one but not more than two additional voting tabulator tenders shall be appointed for each additional tabulator so used. Head moderators, central counting moderators and absentee ballot counters appointed pursuant to law shall be deemed to be election officials.

(c) No election official shall perform services for any party or candidate on election day nor appear at any political party headquarters prior to eight o'clock p.m. on election day.
