How many amps does it take to run a freezer?

A typical modern upright freezer uses 2.3 amps when running. Initial power surges during start-up for a typical upright freezer is expected to be approx. 7 amps. A 15 amp fuse / breaker is commonly recommended for upright freezers. However, many more power hungry upright freezers have a 20 amp recommendation.

How to calculate the current of a coffee pot?

A = W/V Current (A or amps) equals watts (W) divided by voltage (V), or more simply, A=W/V. For example, if you have a coffee pot that is rated at 1500 watts, you can easily calculate the maximum amount of current that coffee pot will draw by dividing that wattage number by 110 volts, which is the voltage available on your standard AC receptacles in your RV. So, if you divide 1500 (watts) by 110 (volts) you end up with the maximum current the coffee pot will draw, or in this case, 1500/110 = 13.6 Amps. Now, remember this is the maximum current the coffee pot will draw. In reality, it will draw a lot less when it is just keeping your coffee warm, but when it is perking the coffee, it can be operating near this maximum current limit. And, considering that your RV’s circuit breakers are usually 20-Amp breakers, this load from the coffee pot, while it’s actively perking, would leave with an additional current capacity just 6.4 amps (20 – 13.6) on that circuit of receptacles. When you understand this way of calculating AC voltage limitations, you will be able to avoid plugging in two high-wattage or high-current appliances on the same circuit and operating them both at the same time.

What does a label on an appliance mean?

All of these devices draw some amount of current while operating, and they, like most common appliances, will typically have a label that lists the maximum wattage the appliance will use when it is operated. But many other devices will only list the maximum current the appliance will draw and not the wattage.

Why are RV circuit breakers rated at different current limits?

These breakers are rated at different current limits to protect the equipment inside the RV, and thus prevent overloading of the RV’s electrical circuits and wiring. If one or more of your AC-voltage circuit breakers “kicks off,” that means the current exceeds what your circuit was designed for.

What devices can be used in an RV?

Common personal devices that campers plug into their RV’s receptacles include cell phone chargers, personal computers, flashlights, TVs, satellite receivers, and portable stereos. All of these will draw some level of current even while not charging a device or operating. Most RVs also use home appliances that draw higher current, including coffee pots, mixers, electric frying pans, electric crock pots, toasters, portable ice makers, and other higher current drawing home appliances, all of which add to your load on your breakers. All of these devices draw some amount of current while operating, and they, like most common appliances, will typically have a label that lists the maximum wattage the appliance will use when it is operated. But many other devices will only list the maximum current the appliance will draw and not the wattage. When one of your breakers kicks out, you need to figure out things like:

What is the maximum wattage of a table lamp?

Example 2: A table lamp - There is no ID plate but we know the maximum lamp wattage that will be used in the lamp is 100w.Our calculation would be 100W divided by 240v = 0.42A + 10% = 0.46AA good fuse for this would be a 1A.A 3A would be fitted as standard by manufacturers.

How to find fuse size?

If you know the mains voltage (which in the UK is slightly variable but assumed fixed at 240v) and the Wattage gained from the appliance ID plate (not from the plug) we can, using a simple calculation, work out the appliance Amperage and so the fuse size (rating). Wattage divided by Volts = Amps.When a figure is obtained from the calculation it is simply a case of adding approx 10% to the value and choosing the nearest fuse to match. This is a more precise method than just guessing 3, 5 or 13Amp and adds greater protection to your appliance, but you do risk blowing the fuse often if the operating or starting current (Amps) are very close to the fuse rating you have selected. See the examples below.

Do new appliances have a fuse?

Generally these days, most new, domestic appliances come with a pre-fitted moulded plug that already incorporates either a 3Amp or 13Amp rated fuse. For example, a table lamp would have a 3A fuse where a washing machine a 13A but rarely will you find anything in between. The reason for this is simply they are the most commonly available sizes and as such are cheaper to buy, whilst meeting the minimum protection required. An incorrect fuse however will continuously blow if under rated or fail to protect your equipment from possible catastrophic meltdown if it is too high.

What Size Cables for Lighting Circuits?

The Cable sizes for domestic lighting circuits is usually 1mm or 1.5mm twin and earth cable (aka two core and earth). In most cases 1mm should be fine but depends on how many lights are on the circuit and how long the cable run is. If quite a few are required or the cable run is over a long distance, then 1.5mm cable should be used to cope with supply demand and voltage drop.

What are the different sizes of cable?
