How to calculate electricity

Calculate Electricity Consumption in 4 Easy Steps

 

Step 01

Watts Per Day

To calculate energy consumption costs, simply multiply the unit’s wattage by the number of hours you use it to find the number of watt-hours consumed each day. For example, let’s say you use a 125 watt television for three hours per day. By multiplying the wattage by the number of hours used per day, we find that you are using 375 watt-hours per day.

125 watts X 3 hours =
375 watt-hours per day

 

Step 02

Convert to Kilowatts

But electricity is measured in kilowatt hours on your electricity bill. Since we know that 1 kilowatt is equal to 1,000 watts, calculating how many kWh a particular device uses is as easy as dividing by 1,000.

375 watt-hours per day / 1000 =
0.375 kWh per day
 

Step 03

Usage Over a Month Period

Now to find out how much that’s actually going to cost you on your electric bill, you’ll have to take the equation a bit further. First you’ll need to figure out how many kWh the TV uses per month.

375 watt-hours per day X 30 days =
11.25 kWh per month
 

Step 04

Figuring Out the Cost

Next, pull out your last electric bill and see how much you pay per kWh. For this example, let’s say you pay 10 pence per kilowatt hour. To find how much the TV is costing you in a month, multiply your electricity rate by the kWh per month that you calculated above.

11.25 kWh per month X £0.10 per kWh =
£1.13 per month
 

Another Example

Here’s another more costly example: Your refrigerator runs 24 hours a day. Most refrigerators consume 300-780 watts of electricity. Let’s assume you bought a model that uses only 300 watts.

300 watts X 24 hours = 7,200 watt-hours per day

7,200 watt-hours per day / 1000 = 7.2 kWh per day

7.2 kWh per day X 30 days = 216 kWh per month

216 kWh per month x £0.10 per kWh = £21.60 per month

 

Common Wattages for Household Appliances

The wattage on appliances or electronics varies by device. Typically, older model appliances use more energy, but newer models tend to be more efficient. You can also purchase energy rating A appliances, which are among the most efficient appliances. 

Coffee maker 900-1200 watts
Microwave 750-1100 watts
Toaster 800-1400 watts
Dishwasher 1200-2400 watts
Washer 350-500 watts
Dryer 1800-5000 watts
Iron 100-1800 watts
Ceiling fan 65-175 watts
Space heater (40gal) 4500-5500 watts
Hair dryer 1200-1875 watts
Laptop 50 watts
Computer monitor 150 watts
Computer tower 120 watts
Television 19″-36″ 65-133 watts
Television 53″-61″ 170 watts

Metal Consumer Units

New non-combustible enclosure requirement for consumer units

The third amendment to BS 7671:2011 (IET Wiring Regulations Seventeenth Edition), which was published in January and comes into effect on 1 July, will include a new regulation requiring consumer units and similar switchgear assemblies in domestic premises to have a non-combustible enclosure.

The wording of the regulation is as follows:

421.1.201 Within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439-3 and shall:

(i) have their enclosure manufactured from non-combustible material, or

(ii) be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12.

NOTE 1: Ferrous metal, e.g. steel, is deemed to be an example of a non-combustible material.

NOTE 2: The implementation date for this regulation is the 1st January 2016, but does not preclude compliance with the regulation prior to that date.

British Standard BS EN 61439-3, mentioned in the regulation, is entitled Distribution boards intended to be operated by ordinary persons (DBO).

Implementation date

As stated in Note 2 to the new regulation, the implementation date for the regulation is 1 January 2016.  This is six months later than the effective date of Amendment 3 as a whole.

The purpose of the delay in implementation is to allow a period of co-existence of both metal- and plastic-enclosed consumer units and to allow time for manufacturers to work existing and new products through their supply chains.  Nevertheless, as is also indicated in Note 2, the delayed implementation does not preclude compliance with the regulation prior to 1 January 2016.

Reason for the new regulation

Regulation 421.1.201 was introduced because of reports from fire investigators of a recent trend of increasing numbers of fires involving consumer units having a moulded thermoplastic enclosure. See Figures 1, 2 and 3.

The cause of the fires investigated was almost invariably found to be resistance heating as a result of poor electrical connections due to poor workmanship or lack of maintenance.  Examples of such poor workmanship are thought to include:

  • failure to tighten neutral conductor connections to the same torque as line conductor connections due to a misconception that neutral conductors carry less current;
  • inadvertently taking cable insulation inside the terminal at a connection, resulting in the securing screw or the clamp of the terminal not making proper contact with the conductor;
  • failure to check factory installed connections for tightness where required to do so by the manufacturer; and
  • tightening connections to an incorrect torque and/or with inappropriate tools.

The crucial importance of checking that all electrical connections are properly made, and of taking remedial action where necessary, should never be forgotten.

Whilst the main cause of fire within plastic consumer unit enclosures is without doubt poor workmanship, other potential causes of fire within plastic consumer unit enclosures are thought to include:

  • the type of internal components, such as where terminations have only one securing screw or are of the ‘cage clamp’ type); and
  • where increased heat transfer to the enclosure is caused by the close proximity to an internal item, such as a neutral bar or a conductor terminated at the neutral bar and protruding above it.

Intent of the new regulation

The intent of Regulation 421.1.201 is considered to be, as far as is reasonably practicable, to contain any fire within the enclosure or cabinet and to minimise the escape of flames.

Requirements to be met by the non-combustible enclosure or cabinet

Regulation 421.1.201 gives the choice of either using a consumer unit (or similar switchgear assembly) having an enclosure manufactured from non-combustible material or using a consumer unit having an enclosure made from some other material, such as plastic, and installing it in a cabinet or enclosure constructed of non-combustible material.  See Figures 4(a) and 4(b).  In either case, certain requirements need to be met by the enclosure or cabinet, as explained below.
