What should an electrician check before New Year's Eve at a client's place?

Added: Monday, 12/22/2025


During the holiday and New Year period, homes, gardens, and commercial spaces are filled with thousands of lights and decorations. Numerous events are organized, during which many electrical devices are used. Energy consumption naturally increases, and installations work harder than usual, which raises the risk of failures, fires, and electric shocks. Are you an electrician? Do you conduct inspections for clients organizing New Year's Eve parties? Here is a guide to the most important areas to verify.

Condition of electrical installations and protections

A thorough inspection of the condition of installations, protections, external sockets, and additional lighting points is essential for a safe and uninterrupted New Year's Eve party. Even if your client's electrical installation has been functioning flawlessly all year, a sudden increase in load and extreme weather conditions can reveal potential weak points. A solid electrical review before welcoming the new year is increasingly seen by users (including homeowners) as an investment in safety and comfort. 

Start by examining the main distribution board. Check if the electrical apparatus, especially circuit breakers and residual current devices (RCDs), is functioning correctly. Loose connections or signs indicating overheating of components are red flags. Under the holiday and New Year's load, there is a risk of short circuits! Measuring the insulation resistance of wires and checking the continuity of grounding are crucial. Assess the condition of the wiring. Aluminum cables in older installations should be replaced with modern copper ones, especially in high-load areas. 

Sockets, extension cords, and power points outdoors

Ensure that the sockets, plugs, and switches used outdoors, including portable sockets, have the appropriate IP protection class. The minimum for equipment used in outdoor conditions under covers is IP44. Check the tightness of the covers, the absence of corrosion, and the functioning of grounding. Look at the extension cords used – are they resistant not only to moisture but also to frost? Test them under load. Ensure that power strips with RCDs are used for connecting multiple electrical devices to one power point. Overloading is the most common cause of electrical installation failures on New Year's Eve. Assess, after reviewing the client's plans, whether the existing circuits will not be overloaded. This can happen when, for example, outdoor lighting, a large electric grill, and a heater are connected to one circuit. If necessary, distribute the load across different circuits or suggest optimal solutions to the client. 

Outdoor and emergency lighting – quick checklist

Various types of lamps and light decorations contribute to the New Year's atmosphere. At the same time, they are a potential source of danger to the safety of the installation and the successful course of the event. Without light, there is no fun. Here is a practical checklist that will help you quickly check outdoor and emergency lighting step by step. 

  • Condition of fixtures and lamps – check for any damaged components and signs of overheating, and assess the quality of the mounting.
  • Appropriate IP protection class – external elements should be adequately resistant to moisture, water, and dust. 
  • Checking connections – electrical connections must be made in a durable and safe manner, without makeshift connections. 
  • Emergency fixtures – test the operation of emergency lighting if it is present at the client's location. It may be equipped with an automatic test that monitors the technical condition and informs about any irregularities.
  • Full load simulation – simultaneously turn on the electrical devices that will be used during the New Year's Eve party to assess the installation's response. 

Finally, prepare an inspection report. If damage occurs on New Year's Eve, the client will be able to more effectively pursue compensation claims from the insurer.

FAQ

1. Should I inspect the installation before New Year's Eve if there have been no problems before?

Yes. The holiday and New Year period is associated with exceptionally high loads on the installation – decorative lights, household appliances, heaters, and audio devices are all operating simultaneously. 

2. What elements of the installation should an electrician check first?

The basis is to check the distribution board: circuit breakers and residual current devices (RCDs) and connections.

3. How to safely use extension cords in the garden during frosts?

Only special outdoor extension cords with rubber insulation, with a minimum protection class of IP44, resistant to frost, are suitable for use in winter conditions. During operation, the extension cord should be fully unwound. Despite being waterproof, it should not lie in water or under snow. 

4. Is it safe to connect multiple devices to one circuit?

Not always. There is a risk of overloading the circuit, which is one of the most common causes of installation failures.

5. Who can conduct an inspection of the electrical installation's condition?

The inspection should be carried out by an electrician with SEP qualifications. The examination ends with the preparation of a report, the validity of which depends on the electrician having the appropriate qualifications and credentials.
