IP44
IP stand for Ingress Protection. It is a rating that describes the protection a fitting has from intrusion of Solid and Liquid material.
The letters IP are always followed by 2 numbers, the first refers to intrusion by solids (1-6) and the second refers to intrusion by liquids (1-8).
For Example a Rating of IP44 would be used on an exterior fitting that may get rained on. Where as an IP68 rating would allow the fitting to be submerged into water, eg a pond light.
The chart below gives a detailed overview of hat each of the numbers represent.

| 3 | Protected against objects > 2.5mm (tools/wires) | 3 | Protection against water spray 60 degrees from vertical |
| 4 | Protected against objects > 1mm (small tools) | 4 | Protection against water spray from all directions |
| 5 | Protected against dust, limited ingress | 5 | Protection against low pressure jets of water |
| 6 | Totally protected against dust | 6 | Protected against high pressure water jets and heavy seas |
