Posted By Topic: socket height

Feb 18 2018 21:57

New to this country. Is it correct when installing a new socket it must be 300mm of the ground? is that to the bottom of flush box?
Also is the same true for a three phase socket?

Feb 18 2018 22:33

Have you checked the wiring rules?

Feb 18 2018 23:30

went through them, (fairly quickly) but could not find anything, I know its in there some where but just a headache trying to find every thing.

Feb 18 2018 23:39

I should add it was an electronic version on a small phone screen, very frustrating, especially when the touch screen is not working correctly.

Feb 18 2018 23:45

The main places with a height restriction are zoned areas in damp locations as detailed in section 6 of AS/NZS3000:2007.

There may also be restrictions in hazardous areas.

my dog ate my phone, it\'s father used to eat my homework so i can\'t read the rules either...

Feb 19 2018 07:44

The only Wiring Rules requirements in AS/NZS 3000 for the height of socket outlets to the floor is clause if it is within 75 mm of the floor the plug must be able to be withdrawn in a horizontal plane; the other is 300 mm min from the floor in damp areas Section 6.

Some countries (UK for one)have minimum distances to the floor for the ease of disabled persons, there is no equal in AS/NZS 3000.

Actually there is a direct equivalent; though not in \"3000\", and guidance rather than requirements. NZMP 6004:1999 Safer Electrical Installations in Homes for Children, the elderly and people with disabilities.

A more modern reference is SNZ HB 4102:2011 Safety in the home. This publication won an award for being written in \"plain english\" so it is very easily to follow.

To the OP...
If you’re slack enough that you CBF looking for such a simple regulation then I’d hate to think what your work practice/compliance is like.
Being new to the country you should have a pretty good idea of 3000 seeing as you would have done the regulations exam!
3000 has a very good index, so make use of it.

Be nice

If you don\'t like the question just don\'t answer.

I was interested any answers.

paulhiggs - Good on you for coming and asking the question.

It\'s very difficult to find a rule which does not exist. So I don\'t know how mf51to1 thinks it\'s such a simple regulation.

I suspect that you might be asking the question, because someone told you there was a measurement of 300mm? If that\'s the case, then they are also in need of some further education.

My advice to you would be to get the PDF version of 3000 and use the keyword search function to try and find information. The keyword \"hits\" often provide some additional learning along the way.

Keep asking questions.

Fair enough, just seemed like another \"i cant be bothered checking so ill just ask here\" type question is the way i took it.
And considering theres already a number of topics on this exact same thing, it does seem a little petty.

NZS4121:2001 (Building design for access and mobility) applies to public buildings and dwellings equipped for people with disabilities.
4.11.4 states that all light switches shall be 900-1200mm above the floor and aligned with doo handles, and sockets 500-1200mm above the floor and >500mm from any corners.
Although this was designed for wheelchair access, able-bodied people who lived in these houses find them convenient. Is there any good reason for putting sockets close to the ground?

Feb 21 2018 10:00

I\'d hate to have all my sockets no lower than 500mm. Multiboxes would be dangling in the air, the vacuum cleaner cord would often be a trip hazard, a number of extension cords would need to be longer, and some nice unobtrusive cords that run under furniture would be far more visible.

Feb 21 2018 17:08

An acceptable solution under the building Code says the following:-

Quote starts

NZ Building Code G9
23 June 2007
Electrical Installations within Domestic Dwellings
NZECP 51 is an Acceptable Solution for electrical installations within domestic dwellings.
Light Switches and Plug Sockets for use by a Person with a Disability

In buildings intended for use by persons with disabilities
, light switches and socket outlets shall comply with the following requirements:

a) All light switches shall be horizontally aligned with door handles.
b) The toggle, rocker, push pad, or push button control of light switches shall project clear of the switch plate.

COMMENT: It is recommended that the width of any push pad or button be no less than 20 mm.
c) Socket outlets in accessible accommodation units shall be fixed between 500 mm and 1200 mm above the finished floor level and at least 500 mm from corners.
At least one room light shall have a bedside switch.

Paragraph 2.0.1 shall not apply in damp situations where the location of the light switch and plug sockets conflicts with AS/NZS 3000.
Quote finshes

This a requirement of the NZ Building Code as an acceptable practice in the circumstances stated.


Feb 21 2018 17:57

I\'m not sure how the conversation strayed into the strict requirements for buildings intended for use by persons with disabilities?

It doesn\'t apply to normal residential, unless the building is required or designed to be an accessible building.


Feb 22 2018 12:06

Let\'s think about making things user-friendly. About 8% of us has a disability and the ageing population with creaky joints hates bending down.
I fitted out a couple of houses to NZS4121 and discovered most of the electrical recommendations are common sense, such as standard light switch positions and having cooker controls on the front so users are not reaching over hot pans. Other sections about kitchen layouts and door access are worth reading too, but a bit off topic.
We followed the same principles in several more new builds including my own home, it just works for most folk.
And I never noticed any multi-boxes dangling on their cords (get real)!

Feb 22 2018 12:11

My message was in response to the question \"Is there any good reason for putting sockets close to the ground?\", not a general objection to the rules for accessible buildings. The key is that there are good reasons for wanting sockets closer to the floor, and it\'s not a safety issue to put them lower as long as you\'re following the rules.

Feb 22 2018 13:52

So since clause G9 of NZBC is a requirement (way more than just an acceptable practice); the full answers to the OP\'s questions are

Is it correct when installing a new socket it must be 300mm of the ground?
No; unless in an \"accessible accommodation unit\" of a a building intended for use by persons with a disability, in which case the Building Code requires socket to be between 500 mm & 1200 mm from FFL.

is that to the bottom of flush box?
A2 it\'s to the edge(s) of the socket outlet

Also is the same true for a three phase socket?

Feb 22 2018 16:55

\"And I never noticed any multi-boxes dangling on their cords (get real)!\"

By and large shouldn\'t need multi-boxes in a new house, with the exception of the home theater/FS TV/Sky etc, which should be plugged into a decent quality Surge Board which will have a 2m Lead.

Feb 22 2018 23:08

SaintAlan, I can assure you that at least two of the multiboxes in my house (and a number at work) have cords shorter than 500mm, although I\'m sure new ones have longer cords. A new build doesn\'t mean the occupant has all new appliances.
And if you\'re running cords under furniture you\'re already on your hands and knees so closer to the floor is probably better.
