Approval of the legislation ITC-52

Approval of the legislation ITC-52

The new Technical Instruction Complementary (ITC-BT-52), the regulation under which loading facilities in buildings will be normalized, was approved last 12 of December in the Council of Ministers, and shall enter into regulation on June 31, 2015.

Next we will make a summary of the relevant aspects of the legislation ITC BT 52.

The Royal Decree 1053/2014 by which is approved a new Technical Instruction (ITC) BT 52 “Facilities for special purposes. Infrastructure for recharging electric vehicles.

For what does this kind of policy exist and why are this ones generated?

The policies exist so that facilities are safe, but nationally there is already a low tension regulation, then why was it so important the appearance of this ITC-BT-52? Well, mainly to take into account considerations which are not taken into the general rules and most importantly in this case, favor the introduction of electric vehicles.

What conditions and technical requirements specifies?

This new complementary technical instruction marks the level of electrification and the numbers of the required recharging points in the new construction parkings, it also marks the brand characteristics of the connectors on each type of facility and makes easer the private management of the charging points without the need to hire a load manager, etc. Therefore this new complementary technical instruction is almost more important for its directives that favour the implementation of the EV than the technical specifications of the facilities.

·         Buildings and parking facilities of new construction:

For projects after the date of publication of the statement (31/12/2014) governed by the law of horizontal property, will be required to project a pre-installation “with, pipes, channels, trays, etc.” for future parking  places for the electric vehicles, where it has to be made an installation of a charging point for every 40 parking places.

·         Buildings and car parkings already made:

These facilities have three years to adapt to the new rules.

It is important to note that one of the important provisions of the draft that was expected to be included in this complementary technical instruction was the retroactive regulations for car parkings and infrastructures of existing recharging points, but this has not been maintained in the final document. This means that none of the existing parkings must adapt to these rules and none of the charging points that are already installed have to adapt either. The sector is awaiting guidance from the ITC-BT-52 that will help to understand some aspects of the rules that are a bit left in the air such as in the case of  new work done in existing installations, this ones will have to adapt to the new ITC altough it doesn´t reach  the expansion of 50% of the installed potency capacity (as it marks the current REBT)

Possible schemes for the installation of charging points

To finish, regarding the schemes allowed to feed the charging equipment presented in this ITC, it is important to note Scheme 2. This scheme allows to power the charging point from the centralization of counters, just downstream of the meter from the output terminals of the Individual branch of housing.

Scheme 1: Schematic collective or trunk with a main meter at the origin of the installation.

Aimed at cargo managers

 2. Individual Scheme with a common counter for housing and the recharging station.

The referral to the charging point comes from the meters box of the counter.

 3. Individual Scheme with a counter for each charging station.

A new meter for the charging point.

 4. Scheme with additional circuit or circuits for the charging of the electric vehicle.

Intended for individual homes, businesses, private garages….

Facilities that require the project

For its implementation, according to the complementary technical instruction approved, the following new facilities require development project:

Group Type of facility Limits
a The ones corresponding to industries, in general P>20 kW
 

b

The ones corresponding to:

– Humid premises, dusty or with  the risk of corrosion;

– Pumps extraction or elevated water,

whether industrial or not.

P>10 kW
 

c

The ones corresponding to:

– Wet places;

– Generators and converters;

– Insulated cables for the heating, excluding housing.

P>10 kW
d – in a temporary way for the power of the machinery in the construction sites.

– in a temporary way in closed premises or open sites;

P>50 kW
e The ones in the buildings mainly for homes, shops and offices, with no consideration of public places, vertical or horizontal construction. P>100 kW by general box of protection
f The ones corresponding to the single-family homes. P>50 kW
g The ones in the car parking’s or parking lots that require forced ventilation. Whatever is the occupation
h The ones in the car parking’s or parking lots that have natural ventilation. Of more than 5 parking places
i The ones corresponding to public places with a lot of people; Without limit
 

 

j

The ones corresponding to:

– Low voltage lines with common support with high voltage;

– Machines for lifting and handling;

– The ones that use special voltages;

– Those designed for the illuminated signs except the facilities that are considered low voltage as set out in the ITC-BT 44;

– Electric fencing;

– Overhead or underground distribution networks;

Without limit of potency
k – Outdoor lighting installations. P> 5 kW
l The ones corresponding to places with risk of fire or explosion, except parking lots or parking. Without limit
m The ones in the operating and intervention rooms. Without limit
n The ones corresponding to pools and fountains. P> 5 kW
z The ones corresponding the infrastructure for recharging electric vehicles. P> 50 kW
  Recharge facilities located outside P > 10 kW
  All facilities that include charging stations planned for the charging mode 4. Without limit
o All those who, not being included in the above groups, the Ministry decides with industrial responsibility, through the timely provision. Accordingly

(P = Power under the facility, taking into account the provisions of the (ITC) BT-10)

It will be not necessary to develop a project for the recharge facilities that run on the installation groups g) and h) that already exist, provided that the new facilities are not included in the group z).

This way, it will be necessary to develop a project of the expansions and modifications of the following facilities:

a)   The expansions of the facilities with the types (b, c, g, i, j, l, m) and significant modifications of those described above facilities.

b)     The expansions of the facilities, that being on the types listed in the table above, would not reach the expected power limits set for them, but that go beyond the power limits once its made the extension.

c)    The expansions of facilities that originally required a project if in one or several expansions is exceeded 50% of the power expected in the previous project.

If a facility is covered by more than one group specified in the table above, we apply the most demanding criteria laid down for such groups.

Inspection of the facilities

It will be object of inspection once executed the installations, their expansions or modifications of importance and this will happen prior to being documented before the competent body of the Autonomous Community, the following facilities of the charging stations for electric vehicles that require the development of a project for their execution.

We recommend reading the instruction since it details many aspects of importance. If you want more information, please consult the regulation here:
