The shore power cord includes a connector plug rated at a first amperage, wherein the connector plug is configured to connect to an electrical power source, and a connector receptacle rated at a second amperage, wherein the connector receptacle is configured to connect to an electrical power receiver, and wherein the connector plug and the connector receptacle are electrically coupled via at least one electrically conductive line. The shore power cord further includes an overcurrent protection apparatus, wherein the overcurrent protection apparatus is positioned along the at least one line, between the connector plug and the connector receptacle, and wherein the overcurrent protection apparatus includes at least one circuit breaker, the at least one circuit breaker having an amperage, the amperage of the at least one circuit breaker being a lower of the first amperage and the second amperage. ## Claims ### Claim 1 A shore power cord, comprising: a single connector plug configured to connect to an electrical power source, and wherein the single connector plug is rated at a first amperage; a connector receptacle configured to connect to an electrical power receiver, and wherein the connector receptacle is rated at a second amperage; wherein the connector plug and the connector receptacle are electrically coupled via a plurality of electrically conductive lines including at least one electrically hot “hot” line; a circuit breaker positioned along the at least one electrically hot line between the connector plug and the connector receptacle; wherein the at least one electrically hot line from the connector plug makes a direct electrical connection to the circuit breaker, and the at least one electrically hot line from the circuit breaker makes a direct electrical connection to the connector receptacle; and wherein the circuit breaker has an amperage rating that corresponds to the second amperage rating of the connector receptacle, such that if the electrical current at the connector receptacle exceeds the second amperage, the circuit breaker trips. ### Claim 2 (depends on 1) The shore power cord as recited in claim 1, wherein the at least one circuit breaker is a waterproof circuit breaker. ### Claim 3 (depends on 1) The shore power cord as recited in claim 1, wherein the first amperage is greater than the second amperage. ### Claim 4 (depends on 1) The shore power cord as recited in claim 1, wherein the connector plug, connector receptacle, circuit breaker and at least one electrically conductive line are weather resistant. ### Claim 5 (depends on 1) The shore power cord as recited in claim 1, further comprising a plurality of electrically hot lines interconnecting the connector plug and the connector receptacle; a separate circuit breaker positioned along each one of the electrically hot lines; and wherein electrically hot lines make direct electrical connections from the connector plug to the circuit breakers and from the circuit breakers to the connector receptacle. ### Claim 6 (depends on 1) The shore power cord as recited in claim 1, further comprising a second connector receptacle with an amperage rating connected to the electrical plug through a second electrically hot line; a second circuit breaker positioned along the second electrically hot line; and wherein the second circuit breaker has an amperage rating that corresponds to the amperage rating of the second connector receptacle, such that if the electrical current at the second connector receptacle exceeds the amperage rating of the second circuit breaker, the second circuit breaker trips. ### Claim 7 (depends on 6) The shore power cord as recited in claim 6, wherein the connector plug, circuit breaker and connector receptacles are disposed in a waterproof housing. ### Claim 8 (depends on 1) The shore power cord as recited in claim 1, wherein the connector plug is rated at 30 amps, and the connector receptacle is rated at 20 amps. ### Claim 9 (depends on 5) The shore power cord as recited in claim 5, wherein the connector plug is rated at 50 amps. ### Claim 10 (depends on 5) The shore power cord as recited in claim 5, wherein one or more of the circuit breakers are rated at 30 amps. ### Claim 11 (depends on 6) The shore power cord as recited in claim 6, wherein the connector plug is rated at 30 amps, and one or both of the first and second connector receptacles are rated at 20 amps.
