Notice how the medial and lateral pectoral nerves penetrate the pectoralis minor muscle to innervate it. Medial to the medial border of the pectoralis minor is the first part of the axillary artery, directly posterior to the muscle is the second part, and lateral to the lateral border of the muscle, is the third part of the axillary artery. The pectoralis minor is used as the reference point for the three divisions of the axillary artery.

the posterior, lateral, and medial cords of the brachial plexus.

Running deep to the pectoralis minor muscle are the nerves and blood supply to the upper limb: The pectoralis minor is important clinically and as a surgical landmark, due to the structures that lie below or deep to the muscle and its tendon. Posteriorly the pectoralis minor is related to the serratus anterior and intercostal muscles, the ribs and several neurovascular and lymphatic structures, described below. Together the pectoralis major and minor, as well as their associated fascia, form the anterior wall of the axilla.

It covers the pectoralis minor, superior to it forming a fascial layer known as the costocoracoid membrane and inferior to it forming the suspensory ligament of the axilla, continuous with the axillary fascia. Found between the two muscles are the lateral pectoral nerve and the pectoral branches of the thoracoacromial artery. Located deep to the pectoralis major and its covering fascia is another connective tissue layer known as clavicopectoral fascia. The installers didn't give me any certificate or anything at the end and just left.The main anterior relation is the pectoralis major muscle, found superficial to the pectoralis minor and almost completely covering it.

It also doesn't make a lot of sense to me that you can install extra sockets, which can carry a lot more amps, but can't install an extra light switch, which usually only carry a couple dozen watts maximum now with LED bulbs.Īlso while I'm here, on a similar topic, I got a new hob and oven and got the store to install them for me since these are restricted/controlled work and need to be certified.

When it says 'where the existing circuit is retained', I take that to mean the full circuit from the distribution box, right? Or is that the individual circuit between the wall switch and the lightbulb? I understand it as the former, but as I said, this part isn't clear to me. The first and last points are clear, but the second is not very clear to me. Provision of an additional socket to an existing radial circuit

Replacement or relocation of light fitting where the existing circuit is retained and Replacement of an electrical accessory such as light switch Examples of Minor Electrical Works include the following: Therefore, Minor Electrical Works can be undertaken by a non-registered party, and do not require the issuance of a Certificate.

Googling about this I've found this PDF from CER, which on page 16 defined what are these minor electrical works: First of all, I'm not a certified electrician but I know what I'm doing, I just don't fully understand the law here in Ireland. I see there are three main categories of electrical work: 'controlled', 'restricted', and everything else, or 'minor electrical works', which should be DIY-able. I'm trying to check which kinds of electrical work are legal to DIY and which aren't.
