The second digit in the IP rating code will indicate how much protection against moist your item will have. The IP rating should be understood before buying, which allows you to ignore the marketing claims. When the surrounding temperature gets too high, the composition melts and allows the spring contact mechanism to break the circuit. A duplex bundle is normally used in situations where only a single 115-volt circuit is required; such circuits are typically provided for low-capacity loads such as streetlights and traffic signals. For three phase electricity supply, circuits will use five wires: earth wire, neutral wire, live wire, line 2 wire, line 3 electrical wire. Ideally, you want a hookup cable that is easy to use every time. You have enough to worry about when you go caravanning, so the last thing you want to do is have to spend hours trying to troubleshoot and issue when the best cables allow you to just plug in to use. Recently the law has changed as the result of a court ruling where 'use' of a vehicle has been defined. This type of hookup is usually used as an adaptor socket lead that’s reserved for indoor use only and not the continual outdoor use that a hook up cable is used for.

It’s important to understand the rating of your cable because to meet the IEE regulations it needs to be a 2.5mm core mains lead. We’d always recommend that if you’re caravanning in the UK that you stick to a 2.5mm cable. It’s important to see whether your hook up cable comes supplied with a warranty because this is often worth paying a little more for if it means that you’re going to secure long term cover. Household sockets aren’t even suitable for moisture, let alone water and rain which you can almost expect if you’re in the UK. Automotive fuses can be mounted in fuse blocks, inline fuse holders, or fuse clips. In North America, fuses were used in buildings wired before 1960. These Edison base fuses would screw into a fuse socket similar to Edison-base incandescent lamps. A cable limiter is similar to a fuse but is intended only for protection of low voltage power cables. It’s important that your caravan hook up cable has adequate protection. Although the campsites electric supply will have a circuit breaker, it’s recommended that you also have your precautions on your mains unit, which will automatically turn off your supply as soon as a fault is detected.

It’s not uncommon for electricians to come across poorly installed plugs that are an ongoing safety hazard. If you browse through many types of websites, you will come across sellers that are offering caravan hook up cables at low prices which might draw you in because it looks like a bargain. This plug was used to connect low-power appliances (and to adaptors from the larger socket types). If it just comes with a blue mains plug with a socket, then there is no protection present. An IP rating is short for the term Ingress Protection mark which is a two-digit grading system that’s ingrained onto the enclosure of electrical items so customers can see how effective the item is at resisting intrusion to unwanted substances. Others were built even further out as part of the protection of trade routes, especially the Silk Road. August 2008: BS 1363-5:2008 "13 A plugs socket-outlets adaptors and connection units - Part 5: Specification for 13 A fused conversion plugs" published. These are still used in consumer units in some parts of the world, but are becoming less common.

The USA have their own wiring colours for electrical circuits, black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC. From looking at the Google Analytics statistics and the questions which land people on this webpage, I often see questions asked such as "how many watts are in 480 volts?", which obviously makes no sense! Twenty-six stations covered an area 320 by 480 km (200 by 300 mi). In March 2006, the United Kingdom government made an amendment to British Standard BS 7671 (Requirements for Electrical Installations), as a result, what are electric cables the change of colour coding for electric cables was considered one of the most significant changes for the electrical industry in modern history. Genuine caravan hookup cables will be orange, making it highly visible. The colour of the cable is very important because it needs to be visible between the grass and gravel at your caravan pitch.
