**15A** power receptacles are the familiar ones found in a residence.((NEMA 5-15, https://en.wikipedia.org/wiki/NEMA_connector#NEMA_5)) They are also the current rating many DIY RVs and vans are built around. | **15A** power receptacles are the familiar ones found in a residence.((NEMA 5-15, https://en.wikipedia.org/wiki/NEMA_connector#NEMA_5)) They can carry 1800W((http://rvservices.koa.com/rvinformation/rvmaintenance/rv-electrical-101.asp)) and are the type of shore power many DIY RVs and vans are built around.((assuming they have shore power receptacles at all)). |

**20A** power receptacles are similar but the "hot" leg has an additional spur.((NEMA 5-20, https://en.wikipedia.org/wiki/NEMA_connector#NEMA_5)) This arrangement **allows 15A plugs to go into 20A receptacles** but **prevents the heavier duty 20A plugs from being used in a 15A circuit**. | **20A** power receptacles are similar but the "hot" leg has an additional spur.((NEMA 5-20, https://en.wikipedia.org/wiki/NEMA_connector#NEMA_5)) This arrangement **allows 15A plugs to go into 20A receptacles** but **prevents the heavier duty 20A plugs from being used in a 15A circuit**. |
Boondockers and vandwellers will likely set up their shore power to run on the 15A. Because of the backward-compatible 20A socket they will be able to use their 15A plugs at both 15A and 20A hookups. | Boondockers and vandwellers will likely set up their shore power to run on the 15A.

Note: using a 10A circuit breaker on the RVs AC breaker box will prevent tripping a residential circuit breaker from tripping when the RVer might not have access to reset it. A 15A breaker might, depending on whether the RV or residential breaker trips earlier. | The 20A outlet is rated for 2400W.((http://rvservices.koa.com/rvinformation/rvmaintenance/rv-electrical-101.asp)) |

A 'dweller can safely power a 15A RV from a 30A outlet with [[http://amzn.to/2irQhRV|an adapter]]. | A 'dweller can safely power a 15A RV from a 30A outlet with [[http://amzn.to/2irQhRV|an adapter]]. |
If the 30A circuit on a 30A/50A pedestal is broken or malfunctioning the camper can use [[http://amzn.to/2hGJNzH|an adapter]] to get power from the 50A circuit.((http://rvbasics.com/techtips/50-to-30-amp-adapter.html)) Note this may incur a price increase from the park. | If the 30A circuit on a 30A/50A pedestal is broken or malfunctioning the camper can use [[http://amzn.to/2hGJNzH|an adapter]] to get power from the 50A circuit.((http://rvbasics.com/techtips/50-to-30-amp-adapter.html)) Note this may incur a price increase from the park. |

The RV can also run off a 15A/20A outlet but would have to be careful about loads (heavy loads like a single A/C unit, electric cooktop, or microwave would have to be run one at a time). | The RV can also run off a 15A/20A outlet with an adapter but would have to be careful about loads (heavy loads like a single A/C unit, electric cooktop, or microwave would have to be run one at a time). |

50A systems are most common in large, luxury RVs with two or more A/C units.((NEMA 14-50, http://www.rv-project.com/resources/nemaconn.php)) | {{ https://greentransportation.info/ev-charging/range-confidence/chap8-tech/img/nema-14-50-wiring-diagram.png?200}} 50A systems are most common in large, luxury RVs with two or more A/C units.((NEMA 14-50, http://www.rv-project.com/resources/nemaconn.php)) The 50A RV power pedestal has //two// 50A 120V legs((http://www.myrv.us/electric/Pg/50amp_Service.htm)) ([[https://en.wikipedia.org/wiki/Split-phase_electric_power|split-phase]]) and can deliver 6,000W of power on each leg.((http://www.myrv.us/electric/Pg/50amp_Service.htm)) |

Althought it is called 50A power it has two 50A legs((http://www.myrv.us/electric/Pg/50amp_Service.htm)) for a combined 100A of power. | 50A to 30A adapters will use one leg of the outlet to feed the RV with 50A. |

**IMPORTANT:** This same connector is used residentially for electric stoves, which use 240v. If you are having a shore power receptable installed ensure the installer knows your RV runs off 120v. | |

| A //shore power port// is designed to let you plug power cables into the side of your van or RV. As discussed above, RVs typically use 30A/50A service -- they use [[https://amzn.to/2TCV4WJ|this kind of port]]. |
| |
| Vans typically use [[https://amzn.to/2VUwDAI|15A ports]]. [[https://amzn.to/2F8SChD|Some are pre-cabled]] so you can plug the inside cable to a [[https://amzn.to/2F7sZxI|power strip]], [[https://amzn.to/2VWXHPQ|breaker box]], or other distribution device. |
