An appliance

[Isetech]

3.3 appliance

machine, tool, device or instrument that is operated by electricity for the purpose of doing work, or for providing heat, light or motion, or in which electrical energy is modified into another form of energy.

An inverter would be regarded as an appliance because it can modify "electrical energy" into anotehr form of energy.

Would a solar panel or battery be refered to as a power supply or an appliance? I see when some people reference regs for batteries and inverters they refer to the units as appliances, for disconnection devices etc.

An appliance uses power from a point of consumption.

A power supply supplies power to a point of consumption.

An inverter with batterias can either be an appliance or a supply depending on the configuration.

If the inverter and batteries are used in the plug and play mode where the inverters output is not connected to the electrical installation, then it's an appliance.

The moment the output of the inverter is connected to the electrical installation, it becomes a supply.

Please help me - Into what form of energy does an Inverter modify electricity ?

An inverter can never be an appliance , not sure why this discussions has come to the fore again as the so called PV installers with no qualification were using this Appliance story as a way around having to be an electrical contractor - That was put to bed and squarely covered under 7.12

@GCE I hear you. For me, however, it's difficult to see how an inverter supplied with a 16A plugtop meant to be plugged into a standard 16 Amp socket outlet can be anything else but an appliance.

It is an inverter , static UPS - Has been that way all the years

We never called a UPS or generator an appliance

Definition is clear that an appliance takes Elec Energy and converts it to another form of energy

@GCE Thanks for that.
As a matter of interest, how would one classify an electric fence energiser ?

So then if a trolly inverter is not an appliance then surely it needs to have the correct protection in the way of circuit breakers and more so an Earth leakage device as they always come with a standard 3 pin socket and not a dedicated ?

Interesting this, thank you

I would classify it as an Electrical Fence energizer - It comes along with it's own set of rules and regs in OHSA


Extract below from OHSA Electrical Machinery Definitions

"electric fence" means an electrified barrier consisting of one or more bare
conductors erected against the trespass of persons or animals;
"electric fence energiser" means electrical machinery arranged so as to deliver
a periodic non-lethal amount of electrical energy to an electric fence connected to
it;
"electric fence system" means an electric fence and an electric fence
energiser;

@GCE thank you. Busy working now but this evening I'm gonna study 7.12 and there might be another query. Please bear with me. 😆😆😆😆

You dont need an ELU or an earth spike, or need to bond the neutral earth, if you use a generator for its intended purpose, the same with a mobile trolley inverter, so long as you dont connect it to an electrical installation.

So then if a trolly inverter is not an appliance then surely it needs to have the correct protection in the way of circuit breakers and more so an Earth leakage device as they always come with a standard 3 pin socket and not a dedicated ?

Ok, spent some time digesting 7.12. ......... 7.12.1.1 clearly states that 7.12 only applies to alternate supplies that supply either a portion of or the whole installation.

The only way that an alternate supply can supply either a portion of, or the whole installation, is if it is connected to the installation somewhere.

A trolley inverter is not.

7.12 therefore does not apply to a trolley inverter or a stand alone inverter supplying let's say a tv and a standing lamp, as the inverter is not connected in any way to the installation.

Am I reading 7.12.1.1 correctly ?


Another interesting point is that 7.12.2.1 states that all forms of alternative devices such as inverters shall comply with the requirements of 6.16.1

6.16.1 is all about fixed appliances.

6.16.1 is all about fixed appliances.

6.16.1 is also all to do with disconnecting devices , position etc -so instead of rewriting numerous pages , multiply times , of it needs a disconnector , don't put on flammable surfaces etc they just refer you back to a clause that is already written

If they wanted an inverter to be referred to as a fixed appliances then they would have a section under 6.16 for inverters like they do with water heaters etc .

This system of referring to other clauses is used through the book - Have a look at 6.9.3.1 / 6.15.4.3 /6.16.5 /6.16.7 /7.9.1.6 / 7.9.3.1.1 which all refer back to a clause in 6.16.1

@GCE. Thanks for that. Got it and agree 100%.

Do you agree that 7.12 is not intended for inverters that are not connected to the installation ?
