Power Supply - is it OK?
Adequate Safe Power Supply- You must ensure you have a safe and adequate power supply, particularly if using electrical equipment outside. Multi point adapters should be avoided. For safety outdoors you should use an RCD or Isolating Transformer. If you are concerned consulting an electrician can be a really good idea! We do not take any responsibility for the safety or suitability of your or your venue's power supply - it is your care.
If the hire equipment stops working, check the power supply.
