The word nominal means the lowest possible safe amount. So, nominal current or nominal voltage is the lowest amount necessary to perform an electrical function like keeping a light turned on.
Answer
The original answer is incorrect. 'Nominal' simply means 'named'. So a 'nominal voltage' is the 'named voltage', as opposed to an 'actual voltage'. For example, the nominal voltage of residential supplies in the UK is 230 V; however, this value is allowed to vary between +10/-6% of the nominal voltage. In other words, a nominal voltage of 230 V may vary between 216 V and 253 V.

Another Answer
Nominal means 'named'. So a nominal voltage is the 'named' voltage. For example, the nominal voltage of the supply system in Britain is 230 V. But its actual value is allowed to vary between 216.2 V and 253.0 V.

For example, in Europe, the 'nominal voltage' is 230 V, but this doesn't mean that the voltage IS necessarily 230 V, because it is allowed, under the various statutes, to vary above or below the nominal value by a certain percentage (between -6% and +10%, for example, in the UK).
The same applies to a nominal current -for example, a kettle's nameplate may specify that the kettle or some other appliance draws a nominal current of, say, 12 A. But, in practice, the actual current will vary due to variations in supply voltage.

What is the Difference maximum unit current draw and nominal unit current draw?
Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
What is nominal current and Load current?
Nominal Current:In respect to Current Transformers, its the allowable current in amperes which can be transmitted by each contact continuously and simultaneously.Load Current:Current flowing through the load.In General...'Nominal' means named. So the nominal current (or voltage) is the named current. For example, a charger may have a nominal current of 100 mA marked on its nameplate, but the actual current drawn by its load (the load current) may only be, say, 75 mA.
What is meant by the term fusing factor?
Fusing factor is the ratio of a fuse's minimum fusing current (the smallest current that will cause the fuse to melt) and the nominal rated current (usually the number in Amps marked on the fuse body).
What is meant by wattless current?
Current flowing through an ac circuit in which power consumed is zero is called wattless current.
What is meant by 1.55 in busbar current calculation?
Busbar current rating for 1 square inch is 1000a.
What is the difference between nominal current and rated current of circit breaker?
They are the same.
What is the Difference maximum unit current draw and nominal unit current draw?
Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
Which of these is calculated in current dollar values?
nominal GDP

Whats does an increase in nominal GDP imply?
When the nominal GDP increases it implies that prices have increased. Nominal GDP is current prices and real GDP takes prices changes into account.
What is meant by the term fusing factor?
Fusing factor is the ratio of a fuse's minimum fusing current (the smallest current that will cause the fuse to melt) and the nominal rated current (usually the number in Amps marked on the fuse body).
What is the formula of calculating increase in real GDP?
Nominal GDP/CPI*100 answer will be in $ amount
Why is Real GDP is preferred to nominal GDP as a measure of economic performance?
nominal GDP uses current prices and thus may over- or understate true changes in output.

How do you calculate nominal GDP at market price?
Nominal GDP is GDP evaluated at current market prices. Therefore , nominal GDP wil include of the changes in market prices that have occurred during the current year due to inflation or deflation. Nominal GDP= GDP deflator.real GDP/100 Real GDP is GDP evaluate at the market price of some base year. GDP deflator --- Using the statistics on real GDP and nominal GDP, one can calculate an implecit index of the price level for the year. This index is called GDP deflator. GDP deflator = nominal GDP/real GDP .100 The GDP deflator can be viewed as a conversion factor that transform real GDP into nominal GDP. Note that in the base year, real GDP is by definition equal to nominal GDP so that the GDP deflator in the base year equal to 100.
