building regs

[5544]

does anyone have a simplistic version of how Part A,B,C,E,F,L and M refer to electrical work. I have read them, and do not find them that specific, or interesting to be truthfull?

i just wanted to go over the main points agian before my assessment.

 

[telectrix]

part p is the most relevant , and the one you need to know most about. they're all about as interesting a read as mein kampf.

The Electricians guide to the building regs, Available from Amazon and the like is the only one that comes to mind,

Building Regulations Parts Applicable to Electrical Work


Part A - Structure
Vertical chases < 1/3 of wall/leaf, Horizontal chases <1/6 of wall/leaf, Chases not damaging wall.


Notches in joists between 0.07 to 0.25 of span <12.5% of thickness.
Holes in joists between 0.25 to0.40 of span <25% of thickness, Holes to be >3 o.d. apart.


Part B – Fire Safety
Positioning and requirements for smoke and heat alarms.
Penetration of fire compartments and the maintenance of the fire resistance rating.
Penetration of fire resistant barriers and maintenance of resistance rating.
Fire stopping of cable penetrations.
Prevention of the spread of fire.


Part C - Resistance to the spread of contaminants and moisture
Prevention of water / contaminants from entering through external cable penetrations.
Prevention of water entering other areas from wet rooms.


Part D cavity insulation
Not normally applicable.


Part E – resistance to the passage of sound
Maintenance of the sound resistance properties of walls and ceilings when making penetrations through sound resistant barriers. Both between dwellings and within dwellings.


Part F – Means of ventilation
Requirements for minimum flow rates in kitchens (60/30l/s), utitilty rooms (30l/s), bathrooms (15l/s) and toilets (6l/s) for intermittent extract ventilation.
Ventilation of rooms without purge ventilation (windows/doors) (15min overrun, no natural light operated by light switch).
Cooker hood heights (450mm-750mm from hob).
Air flow through rooms.
Applicability to new and existing dwellings.


Part G – sanitation hot water safety and water efficiency
Not normally applicable


Part H – Drainage and waste disposal
Not normally applicable.


Part J – Combustion appliances and fuel storage systems
Not normally applicable.


Part L1A – Conservation of Fuel and power in new dwellings
Mainly use of energy saving lighting 75%: >45lm/W (if >5W).
Also external lighting to be photocell + movement sensor controlled or energy efficient.


Part L1B – Conservation of Fuel and power in existing dwellings
Mainly use of energy saving lighting in area worked on 75%: >45lm/W (if >5W).


PartL2A and PartL2B Conservation of Fuel and power in new / existing non dwellings
Not applicable to Part P.


Part M - Access to and use of buildings
Generally just height of switches and sockets >450mm<1200mm.
Consumer units accessible.
Accessibility of switches, outlets and controls –Height, labelling, consistent location, visual ease and lack of obstruction. Some exceptions (floor sockets).


Part N – Glazing safety
Not applicable.


Part P – Electrical safety
Design, install, inspect and test in accordance with BS7671. Work in accordance with H&S requirements.
Kitchen as a specific location. Notify building control for certain higher risk work, or be member of a self certification scheme.
Definitions of notifiable work.

Just had my Elecsa assessment this morning with John Wormald, nice chap and very helpful. Full pass along with no observations or non conformities.


Questions did include some on building regs Part C,F and P along with the usual 17[SUP]th[/SUP] BGB etc.


As long you can show you know what you are on about and can find the relevant info then you should be OK, also as per above The Electricians Guide to the Building Regs covers all you need to know.

Nice of you to take the time to do this, I'm sure it will be appreciated by all , and you've just saved the OP in the region of £20.

Thank you, doesn't cover everything in detail but covers the main points, bit sparse on part P but we all know everything about that!

:8: You're welcome. Keep up the good work. I downloaded all the approved docs but can never find them when I want them lol.
